Question

triangle BCD is a right triangle the length of the hypotenuse is 20 cm the length of one of the legs is 15 cm what is the length of the other leg​

Answer 1

13.22

Explanation:

The eqtn is

hypotenuse^2 = leg^2 + leg^2

20^2 = 15^2 + L^2

400 = 225 + L^2

L^2 = 400 - 225 = 175

L = √175 = 13.22
