Question

A right triangle has legs measuring 20 in. And 28 in. What is the length of the hypotenuse?

A. 8.0
B. 19.6
C. 34.4
D. 1184.0

Answer 1

C. 34.4

Explanation:

Answer 2

h^2 = x^2 + y^2
where h is the hypotenuse, x and y are legs.

h^2 = 20^2 + 28^2
h^2 = 400 + 786
h^2 = 1184
h = sqrt(1184)
h = 34.4 in.
