Question

The leg of a right triangle is 5 ft and the hypotenuse is 10 ft. What is the length of the missing side? (Round your answer to the nearest tenth)

Answer 1

8.7

Explanation:

Because the triangle is right, we can use the Pythagorean theorem to find the length of the other leg.
5^2+x^2=10^2
25+x^2=100

x^2=75

x=5 sqrtc3, which rounds to

8.7
