Question

The hypotenuse of a right triangle measures 8 cm and one of its legs measures 4 cm.

Find the measure of the other leg. If necessary, round to the nearest tenth.

Answer 1

4√3 (about 6.9) cm.

Explanation:

In a 30°-60°-90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg.

Here, the length of the longer leg is 4√3, or about 6.9, cm.
