Question

The hypotenuse of a right triangle measures 15 cm and one of its legs measures 4 cm.

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

Answer 1

14.5 cm

Explanation:

Pythagorean theorem: a^2 + b^2 = c^2

c = hypotenuse (15)

to solve for b (other leg), the equation is b^2 = c^2-a^2

15^2 - 4^2 = 209

`√(209)` = approx. 14.5

the other leg is (rounded to the nearest 10th) 14.5 cm
