Question

Suppose a right angle triangle has one leg that measures 2cm its hypotenuse measures 8cm. Determine the leingth of its other leg.

Answer 1

Explanation:

Use Pythagorean theorem for right triangles

hypot^2 = leg1 ^2 + leg2 ^2

8^2 = 2^2 + leg2 ^2

sqrt (8^2 -2^2 ) = leg2

sqrt (60) = leg 2

2 sqrt(15) cm = leg2
