Question

Pythagorean theorem..

Answer 1

`{\huge{\underbrace{\bf{\pink{Answer}}}}}`

Length of missing leg = 12 km

Using Pythagoras theorem

a² = 15² - 9²

a = √ 225 - 49

a = √144

a = 12 km

HOPE IT HELPS..

Answer 2

By using Pythagoras Theorem:-

(Hypotenuse)² = (Base)²+ (Perpendicular)²

Taking, Hypotenuse As H

Base As B

Perpendicular As P

_________________________

Solving The Question

H²= B²+ P²

`15 {}^(2) = 9 {}^(2) + p {}^(2) \\ \\ p {}^(2) = 15 {}^(2) + 9 {}^(2) \\ \\ p {}^(2) = 225 - 81 \\ \\p {}^(2) = 144 \\ \\ p = √(144) \\ \\ p = 12`

Hope This Helps You ❤️
