Question

A) in a right-angled triangle, if hypotenuse is 20 cm and the

ratio of the other two sides is 4:3, find the sides.​

Answer 1

Explanation:

Ratio = 4 :3

Other two sides = 4x , 3x

Pythagorean theorem

(4x)² + (3x)² = 20²

16x² + 9x² = 400

25x² = 400

x² = 400 ÷ 25

x² = 16

x = √16

x = 4 cm

4x = 4*4 = 16

3x = 3*4 = 12

Sides = 16cm , 12 cm
