Which equation can be used to find the measure of angle LJK?

O sin(x) = 10/15
O sin(x) = 15/10
O cos(x) = 10/15
O cos(x)= 15/10

Answer:

54 is the hypotenuse due to being the longer side(s).
54 ^2=2916 / 51^2=2601 / 22^2=484 = 2916=2601+484 // 22^2+51^2>54^2

Option B.

Answer:

y/2

Step-by-step explanation:

(x+3)/3 = (y+2)/2

x/3 + 1 = (y+2)/2

x/3 = (y+2)/2 - 1

= (y+2-2)/2

= y/2

Answer: 158

Step-by-step explanation:

Okay so the total is 9 5/10.

Each party goer needs 6/10

So 95/10 / 6/0=. 95/10x10/6

=950/6 = 158.

Answer:

y=3x+4

Step-by-step explanation:

This is one equation.

Answer:

y=-5/3x+13.

Step-by-step explanation:

As a line that is perpendicular to anoher line has a slope that is the negative reciprocal of the line's original slope, we know that the slope of our new line is -5/3. As it passes point (12, -7), we can use the point slope formula which is y-y1=m(x-x1). So plug in, y+7=-5/3(x-12) and that gives us y+7=-5/3x+20 which gives our final answer of y=-5/3x+13.

Answer:

see images

Step-by-step explanation:

For all of these questions it helps to know the special right triangle, the 30°-60°-90° triangle. There is a special shortcut to find the sides of the 30°-60°-90° triangle.

For question4 and 5, these are equilateral triangles so the angles are all 60° So if you drop the height, it makes two 30°-60°-90° triangles. ***The short leg is HALF the hypotenuse or the hypotenuse is DOUBLE the short leg. The long leg is the short leg × sqroot3.***

This shortcut, special rt triangle info is used in all three of your questions. See image. Then you will have base and height or the apothem and side length for the Apothem Area formula:

A = 1/2 a•s•n

where a is the apothem, s is the side length and n is the number of sides. It looked like you already used this formula. See image.

Answer:

d

Step-by-step explanation:

surface area of cylinder=2πr(r+h)

2*3.14*4(4+7)

25.12*11

276.3in²

Answer:

Step-by-step explanation:

2πrh+2πr^2 is the formula for finding the surface area of a cylinder.

Since the question said to use 3.14 for pi,

2 * 3.14 * 4* 7 + 2*3.14*16

= 175.84 + 100.48

= 276.32 in^2

So, the answer is d, 276.3 (rounded to 1 decimal place)

Answer:

this question isn't quite clear, is the diagram of the triangle necessary for me to answer this question ?

Step-by-step explanation:

but by simple analysis,

since the "unknown" is b

option (a) which is 42 + b2 = 52 is the best equation.

because we are looking for the value of "b", therefore there should be letter "b" in equation we're going to use. hope you understand...

Answer:

x

Step-by-step explanation:

Answer:

[tex]x\sqrt{2} = c[/tex]

Step-by-step explanation:

The Pythagorean theorem tells us that [tex]a^2+b^2=c^2[/tex], where a and b are the legs of a right triangle. If the length of each leg is x, we know by applying the theorem that [tex]x^2+x^2=c^2[/tex], so [tex]2x^2=c^2[/tex]. Applying the square root on both sides we get [tex]x\sqrt{2} = c[/tex]

Answer: a+51=90, a+51+90=180, 39

Step-by-step explanation:

a+51=90 works because the angles add to form a right angle.

a+51=180 does not work because the angles add to form a right angle, not a straight angle.

a+51+90=180 works because all those angles add to form a straight angle.

a+90=180 does not work because the unknown in this situation refers to a+51, not just a.

Solving the equation, we get a=39, so 39 is also an answer.

Answer:

B. a rectangle

Step-by-step explanation:

A cross section is the new face you see when you slice through a 3D figure. So if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section. Similarly, if you slice parallel to a triangular base then your cross section will be a triangle.

Hope this helps and God bless!

Step-by-step explanation:

I think Its D because In the rectangular base its not equal sides like a square so it would be more be like sides that are not perpendicular.

Pfffttttt- Amateurs, it is quite simple really. Take a nice long look. In the picture is he answer. And I was just joking around, even I had to use a calculator for the answer.

Step-by-step explanation:

Put the x's together, the negatives and the positives.

Answer:

x   y

2   1

4   2

6   3

Step-by-step explanation:

For each x-value, y is half of it.

Divide each x-coordinate by 2 to find the corresponding y-coordinate.

x   y

2   1

4   2

6   3

Step-by-step explanation:

Since y=1/2(x)

x y

2 1

4 2

6 3

Answer:

B. y = -x – 1

Step-by-step explanation:

calculate slope  =

y2-y1   =  -5- (-2)  =  -3

x2-x1   =   4 - 1     =   3

m (slope) = -3/3 =  -1

using points (1,-2) for calculating y-intercept:

y = mx + b

-2 = -1(1) + b

-2 = -1 + b

-1 = b

b = -1

answer is B   y=  -x - 1

The two cones are not congruent because one of the cones is oblique in nature.

Congruent shapes are identical in size and shape. To put it another way, if you hold an object or element in a mirror, the picture you get is congruent to the object.

However, two figures may seem to be identical, but one side or angle in one figure may deviate significantly from the other. The easiest technique to assess sides and angles to check if they are equivalent or congruent is to use markings on figures.

When we apply that technique to the two figures, we realized that the two cones are not congruent because one of the cones is oblique in nature, this resulted in a difference in the slant height of the cones.
