Answer:
A. x = 4; B. x = 6; y = 24
Step-by-step 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
