The trapezoids are similar, find

Answer 1

X = 7

Explanation:

7 + 1 = 8

7 - 3 = 4

4 is half of 8

Answer 2

x = 7

Explanation:

To find the value of x we can use similarity ratio

3/6 = (x-3)/(x+1) cross multiply expressions

3x + 3 = 6x - 18

3 + 18 = 6x - 3x

21 = 3x divide both sides by 3

7 = x
