Answer:

  15

Step-by-step explanation:

We assume you mean that ...

  ∠1 + ∠2 = 90°

  60° + 2x° = 90° . . . . given values for the angles

  2x° = 30° . . . . . . . . . .subtract 60°

  x = 15

1. if m&lt;b = 60 what is AB<br><br><br>2. if m&lt;b =45 what is the perimeter of the trapezoid.​
nika2105 [10]

Answer:....

Step-by-step explanation:

first we need to find the base of the triangle, so the total is 20, they also give us 12, so we subtract 20-12=8 now divide. 8/2=4. Now we use the 4 and the 60. We use SOH-CAH-TOA, they give us the base now we need to find AB which is the hypotenuse. So we take out the TOA, and the 4 is the adjacent so we take out the SOH, we have CAH now, so we use cos. Now equation time....

cos60=\frac{4}{x}   since x is the bottom we switch \frac{4}{cos60}, which equals 8. AB=8.

Now to find the perimeter. We still use the 4 to find the hypotenuse so we  can find the outside side. For this one they tell us to use 45, so now lets see what method we use. SOH-CAH-TOA. We need the hypotenuse and they give us the adjacent, so we use cos again. Now setting up the equation...

cos45=\frac{4}{x}    x is at the bottom again to we switch.

\frac{4}{cos45}   which equals to 5.657 or you can round it. Now we add everything.

20+12+5.657+5.657= 45.314 or you can round it to 45.

A cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height. Using 3.14 for pi, which of the fo
muminat

Answer:

The volume of the cylinder is 6,104.16 square meters.

Step-by-step explanation:

Given that a cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height, to determine, using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder, the following calculation must be done, knowing that the volume of a cylinder is determined by multiplying Pi by the height by the radius squared, and that the diameter of a circle is twice its radius:

3.14 x 6 x (6x3) ^ 2 = X

18.84 x 18 ^ 2 = X

18.84 x 324 = X

6,104.16 = X

Therefore, the volume of the cylinder is 6,104.16 square meters.

Find the midpoint of the segment with endpoints at A(3, 11) and B(7,3).
bonufazy [111]

Answer:

The answer is

<h2>(5,7)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(3, 11) and B(7,3)

The midpoint is

M = ( \frac{3 + 7}{2}  \:  , \:  \frac{11 + 3}{2} ) \\  = ( \frac{10}{2}  \: , \:  \frac{14}{2} )

We have the final answer as

<h3>( 5 , 7)</h3>

Hope this helps you
