Question

Given the diagram below, solve for x. Enter only a number rounded to the nearest tenth

Answer 1

x = 60 cm

Explanation:

using Pythagoras theorem which states that:-

Hypotenuse (h)² = perpendicular (p)² + base (b)²

• h = 100 cm
• b = 80 cm
• p = x

100² = 80² + x²

100² - 80² = x²

10000 - 6400 = x²

3600 = x²

x = 60 cm
