Question

One of the legs of a right triangle measures 16 cm and the other leg measures 8 cm. Find the measure of the hypotenuse. If necessary, round to the nearest tenth.

Answer 1

17.9

Explanation:

Use the Pythagorean theorem, c²= a² + b². We can rewrite it as c = √(a² + b²), a=16 and b=8. Plug it in as c = √(16² + 8²) then simplify.

c = √(16² + 8²)

c = √(256 + 64)

c = √320

c≈17.9 (rounded to the nearest tenth)
