Solve for x plz.aaaa

Answers

Answer 1

Okay!

All we need to do to solve for x is to set up an equation!

the equation 3x + 4 represent the number of degrees of the bottom angle

→To set up the equation, however, we must find what the bottom angle is!

→This is easy since we know that all triangle are 180°

→The diagram already gives us to angles, so to find the third angle, we use simple subtraction

*the little corner with the red square is always 90°

180 = 90 + 50 + ?

? = 180 - 90 - 50

? = 40°

The angle is 40° !

→Now we can finally find x!

→To find x, we just set the equation they give us equal the degrees of the angle that we just found

3x + 4 = 40°

SOLVE !

3x = 36

x = 36/3

x = 12

We did it! Hope I helped ! :)

how do I do this I'm confused

Answers

Answer:

The interior angles of any triangle equal 180. Triangle CDF is an equilateral triangle meaning all of its angles are the same. 180/3=60

Each angle of triangle CDF is 60

1.m<CDF=60

____________________________________________________________

Isosceles triangles have the 2 base angles the same value while the other angle is another value. IN that instance, the m<a = m<f and the m<a + m<f + m<b=180°

If we find one of the angles of ABF then we can find all of them.

the m<AFB + 35° + m<CFD + m<DFE=180°

we know that the m<CFD is 60

35+60+m<AFB + m<DFE=180

95+m<AFB + m<DFE=180

LEts look at the angle AFD

AFD is 150° and since m<AFD and the m<DFE are supplementary, the angle of DFE is 30

lets test it:

if m<DFE is 30 then

95+m<AFB + 30=180

125+m<AFB=180

m<AFB=55

therefore the m<BAF would also be 55 and the m<ABF would be 70

m<ABF=70

This is because the interior angles of any triangle add up to 180°

A diver jumps from a cliff that is 48.5 feet above the surface of the water. She stops descending 12.5 feet under the water. What was the total distance of her jump?

Answers

Answer:

61 ft

Step-by-step explanation:

I'm assuming that the diver simply walked off the cliff since we were not given any information about the jump itself.

If the distance between the cliff and the surface of the water is 48.5 feet, and if the distance between the surface of the water and the place where the diver stopped descending is 12.5 feet, you would add those two distances up.

48.5 ft + 12.5 ft = 61 ft

The total distance of her jump from her was 61 feet.

Given that a diver jumps from a cliff that is 48.5 feet above the surface of the water, and she stops descending 12.5 feet under the water, to determine what was the total distance of her jump, the following calculation must be performed:

The height of the cliff and the depth at which it reached under the water must be added.

48.5 + 12.5 = X 61 = X

Therefore, the total distance of her jump from her was 61 feet.

The illustration below is an example of a semi-regular tessellation.
A. True
B. False

Answers

I think it would be B.False

The illustration below is a semi-regular tessellation is a false statement.

What is Tessellation?

Tessellation is defined as the process of covering of a surface or a plane using the geometric shapes.

One geometric shape will not overlap with the other and there will not be any gaps in between.

There are regular tessellations as well as semi-regular tessellations.

Regular tessellations are the tessellations which are made using only a single type of the polygon to cover the entire surface.

Whereas in semi-regular tessellations, two or more regular polygons are used such that each vertex is the same to cover the surface.

Here, the illustration contains only one type of polygon which are tiled to each other with out any gaps.

It is actually regular tessellation.

Hence the statement that the illustration is semi-regular tessellation is incorrect.

Step-by-step explanation:

If its a right angle it is 90 degrees

Answer:

x=16

y=27.7

Step-by-step explanation:

In a 30-60 right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.

x is the side opposite the 30 degree

so x=32/2=16

let's use pythagorean theorem to find y

x^2+y^2=32^2

y^2=32^2-x^2

y^2=1024-16^2

y^2=1024-256

y^2=768

y=√768

y=27.7

Find all solutions to the equation $x^2 - 8x = -16$.

Answers

Answer:

x = 4

Step-by-step explanation:

x^2 - 8x = -16

Add 16 to both sides.

x^2 8x + 16 = 0

This may be the square of a binomial.

x^2 is the square of x

16 is the square of 4 and -4.

Let's check the middle term:

2ab = 2(x)(-4) = -8x

Yes, it is the square of a binomial.

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x - 4 = 0 or x - 4 = 0

x = 4 or x = 4

Which trigonometric functions are undefined when x = 0?

Answers

The trigonometric functions that are undefined when x = 0:

cot(x) and cosec(x)

We need to write the trigonometric functions are undefined when x = 0.

We know that the trigonometric functions are : sine, cosine, tangent, cotangent, secant and cosecant.

For angle x the trigonometric functions would be,

sin(x), cos(x), tan(x), cot(x), sec(x), cosec(x)

We know that, when x = 0,

sin(0) = 0 and cos(0) = 1

tan(x) = sin(x) / cos(x)

So, tan(0) = 0

cot(x) = cos(x)/sin(x)

cot(0) = 1 / 0

cot(0) = undefined

Also, sec(x) = 1/cos(x)

so, sec(0) = 1

And cosec(x) = 1/sin(x)

so, cosec(0) = 1/sin(0)

cosec(0) = 1 / 0

i.e., cosec(0) = undefined

Therefore, the trigonometric functions that are undefined when x = 0:

cot(x) and cosec(x)
