Question

The figures in each pair are similar. Find the value of each variable. Show your work.

Answer 1

A. x = 4; B. x = 6; y = 24

Explanation:

The corresponding sides of similar figures are proportional to each other.

A. Rectangles

x/2 =16/8 Multiply each side by 2

x = 2 × 16/8

x =4

B. Triangles

x/18 = 4/12 Multiply each side by 12

x = 18 × 4/12

x = 6

y/8 = 12/4 Multiply each side by 8

y = 8 × 12/4

y = 24
