Question

One of the legs of a right triangle measures 6 cm and its hypotenuse measures 9 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

Answer 1

6.7 cm

Explanation:

In a right-angled triangle, a ² + b ² = c ²

call the missing side b.

6² + b² = 9²

b² = 9² - 6²

= 81 - 36

= 45.

b = √45

= √(5 X 9)

= √5 X √9

= 3 √5

= 6.7 cm to nearest tenth
