The length of the unknown side of the right triangle is 13

A right triangle (American English), sometimes known as a right-angled triangle (British), is a triangle with one angle that is a right angle (i.e., a 90-degree angle), or two sides that are perpendicular. The link between is the basis of trigonometry.

between the right triangle's angles and sides.

The side across from the right angle is the hypotenuse (side c in the figure). Legs are the sides closest to the ideal angle (or catheti, singular: cathetus). The side a that is next to angle B and across from angle A is referred to as side b, and the side a that is next to angle A and across from angle B is referred to as side a.

Right triangles are referred to as Pythagorean triangles and their side lengths as Pythagorean if all three of their sides are integer lengths.

Using the law of sines, it is found that the distance from the farthest soccer player to the goalie is 14.723 yards.

Given,

The distance between the two players = 10yards

The angle from each player to the goalie is 64° and 75°, respectively

We have to find,

the distance from the farthest soccer player to the goalie.

In this problem, considering that the sum of the internal angles of a triangle is of 180º, the angle that the goalie makes with the players is given by:

∠A = 180-(∠B+∠C)

∠A = 41°

Using Sine rule

AC/Sin B = BC / Sin A

AC = 10yrd*Sin75°/Sin41°

AC = 14.723 yards

The farthest distance is of 14.723 yards.

Explanation:

After 1 stage, the depth is -340+60*1 = -280 meters. In other words, it's 280 meters below the surface.

After 2 stages, the depth is now -340+60*2 = -220 meters

After 4 stages, the depth is -340+60*4 = -100 meters

After n stages, the depth is -340+60n. Set this equal to zero and solve for n.

-340+60n = 0

60n = 340

n = 340/60

n = 5.667 approximately

This rounds to n = 6

After n = 5 stages, the depth is -340+60n = -340+60*5 = -40 meters

After n = 6 stages, the depth is -340+60n = -340+60*6 = 20 meters, so the submarine is now at the surface. Of course the sub cannot fly to a height of 20 meters above the ocean's surface, so the highest it can go is 0 meters at the surface itself. This means the 6th stage is a movement of 40 meters (instead of 60 meters).

According to the solving the dimensions of the triangles are as follow:

a . 29

b. 58

c. 57

A mathematical space's dimension is defined informally as the smallest number of coordinates required to specify any point within it. Thus, a line has a dimension of one since only one coordinate is required to identify a point on it - for example, the point at 5 on a number line.

2-D shapes really had no thickness and they can only be measured on two sides. Two-dimensional objects include the square, circle, rectangle, and triangle.

x=length of the shortest side

2x=length of another side

x+28=length of the third side

144=x+2x+x+28

144=4x+28

144-28=4x

116=4x

x=116/4

x=29 feet (one side)

Putting the value of x to find second side

2x=58 feet (second side)

x+28= 57 feet (third side)

the perimeter of the triangle = sum of all the sides

                                                = 29+58+57

                                                =144

Expressions in component form for the position vectors having the  polar coordinates are:

a) -12 cos(40)i + 12sin(40) j = -9.19i + 7.71j

b) 3cos(40) i + 3 sin(40) j = 2.29i + 1.92j

c) -24cos(48)i - 24sin(48) j = -16.059i - 17.83j

Use one or more of the following equations: cos=xr, sin=yr, tan=yx, and r=x2+y2 to convert rectangular coordinates to polar coordinates.

The polar coordinate system is indeed a two-dimensional coordinate system in which the distance from a reference point and the angle from a reference direction are used to determine each point's location on a plane. The polar axis is the ray emanating from the pole inside the reference direction. The pole is the point of reference.

Let the +x and +y represent, respectively, the unit vectors represented by I and j.

(a) 12.6 m, 130° counterclockwise from the +x axis [tex]\overrightarrow{\mathrm{R}}[/tex]= m.

    -12 cos(40)i + 12sin(40) j

If we shift the origin without changing the direction and point P(x, y) is changed to P(X, Y) then the new coordinates will be x = X + h and y = Y + k.

Shifting of origin is the phenomenon of changing the coordinates of the origin which is generally (0, 0) to another point which has coordinated (h, k). This phenomenon is usually carried out graphically. This is done when there is difficulty to solve the problems in coordinate geometry when we take the origin at (0, 0).

If we shift the origin which is at P(x, y) to another point (h, k) then the coordinates of new point P(X, Y) will be

x = X + h and y = Y + k

If h is positive, then coordinates will be x = X + h and if h is negative then coordinates will be x = X - h. If k is positive, then coordinates will be y = Y + k and if k is negative then coordinates will be y = Y - k.

the cost of 4 dozens of buttons will be $ 6 and the organizers can buy 216 buttons for $ 27.

We are given that:

Cost of 48 buttons = $ 6

48 buttons = $ 6

Divide both sides by 48:

1 button = $ 6 / 48 = $ 1 / 8

Now, the cost of 4 dozen buttons will be:

4 dozen buttons = 12 × 4 = 48

So, the cost will be 4 6 only.

For $ 27, the organizers can buy:

Number of buttons = 27 ÷ 1 / 8

Number of buttons = 27 × 8

Number of buttons = 216 buttons.

Therefore, the cost of 4 dozens of buttons will be $ 6 and the organizers can buy 216 buttons for $ 27.

A circle with a circumference of 615.44 units has a radius of 98 units.

A circle is a round closed figure where all its boundary points are equidistant from a fixed point called the center.

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant [tex]\pi[/tex] and the diameter of the circle.

C = [tex]\pi[/tex]D

The diameter (D) is the distance across the circle through the center, it is a line that meets the circumference at both ends and it needs to pass through the center. On the other hand, the radius (r) of a circle is the distance from the center of a circle to any point on the circumference of the circle. Radius is half of the diameter.

If r = 1/2 D, then

D = 2r

Evaluating the value of Din the formula of the circumference,

C = [tex]\pi[/tex](2r)

C = 2[tex]\pi[/tex]r

Using the value of [tex]\pi[/tex] as 3.14 and the circumference as 615.44 units,

evaluate the equation.

C = 2[tex]\pi[/tex]r

615.44 = 2(3.14)r

r = 615.44/ (2*3.14)

r = 98 units

The length of the hypotenuse AB is approximately 6.53 units.

In a right angled triangle the side opposite the right angle or the largest side is called the hypotenuse of the triangle.

The length of the hypotenuse is calculated using trigonometric ratios. If in a right-angled triangle, the base angle is θ then:

In the given figure we see in ΔABC

AB is the hypotenuse. ∠BAC = 40 ° AC is the base and BC is the perpendicular.

(The side that contains the given angle is the base and the side opposite the given angle is taken as perpendicular)

Now cos ∠BAC = BC ÷ AB

or, cos 40° = 5 ÷ AB

or, AB = 6.527...

or, AB ≈ 6.53

Hence the value of AB is approximately 6.53 units.

Answer:

x = 1/2 or 0.5

Step-by-step explanation:

4 • ((2x • (2x - 1)) -  (2x - 1))  = 0

The rule says: To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is  (2x-1)  and the exponents are :

         1, as  (2x-1), is the same number as  (2x-1)1

and   1, as  (2x-1)  is the same number as  (2x-1)1

The product is therefore,  (2x-1)(1+1) = (2x-1)2

 4 • (2x - 1)2  = 0

4.2      Solve  :    (2x-1)2 = 0

 (2x-1) 2 represents, in effect, a product of 2 terms which is equal to zero

For the product to be zero, at least one of these terms must be zero. Since all these terms are equal to each other, it actually means:   2x-1  = 0

Add  1  to both sides of the equation :

                     2x = 1

Divide both sides of the equation by 2:

                    x = 1/2 = 0.500

Answer:

x = 1/2.

Step-by-step explanation:

4 (2x (2x - 1) - 1 (2x - 1)) = 0

(2x (2x - 1) - 1 (2x - 1)) = 0

(2x - 1) is common to both parts.

(2x - 1)(2x - 1) = 0

2x - 1 = 0

x = 1/2.
