Question

In the following diagrams calculate the

sides marked with letters x and y.
All dimensions are in cm.

Answer 1

x ≈ 6.5 , y ≈ 12.1

Explanation:

(2x)² + (10.2)² = (16.5)²

4x² = 272.25 - 104.04

x² = 168.21 ÷ 4

x = √(42.0525) ≈ 6.5

y² = 42.0525 + 104.04 = 146.0925

y = √(146.0925) ≈ 12.1
