Question

Quadrilateral ABCD ~ Quadrilateral EFGH
What is the value of x?

Answer 1

x=4

Explanation:

are two similar figures, so we can solve with a proportion between the sides

8 : x = 12 : 6

x = 8 × 6 ÷ 12

x = 4

Answer 2

4

Explanation:

AB/EF = BC/FG

8/12 = x/6

Cross multiply.

12x = 6 × 8

2x = 8

x = 4
