Which of the following is the area of the special trapezoid if ab = 10, cd = 10, and the height is 8? 40 units2 80 units2 400 units2 800 units2

Step-by-step explanation:

We know that the area of a trapezoid is given by :-

, where a and b are the opposite sides and h is the height of the trapezoid.

Now, the area of the trapezoid is given by:-

Hence, the area of the trapezoid =

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
