I need help, I can figure out one but don’t know how to find the top base. I would love an explanation to make it easier for me

Step-by-step explanation:

Since a trapezoid has 4 sides, the sum of the angles is 360 degrees.

The sum of the bottom two angles is 82*2 = 164.

360-164 = 196.

Dividing that by 2, because the two angles should be equal, we have that Q and T are both 98 degrees.

Now, you could've done it a lot faster just by noticing that an isosceles anything is symmetrical across at least one line. Here, if you cut through the midpoints of QT and RS, the trapezoid is symmetrical on both sides.

So T = 180-82=98. To explain how I got this, if you cut through the midpoints, you'd get another trapezoid with 2 right angles. I attached a picture.

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math
