Question

2. What is the length of the unknown leg of the

right triangle rounded to the nearest tenth of
a foot?
2 ft
8.2
9 ft

Answer 1

See below. The answer is 8.8 feet, but none of the options offers this value.

Explanation:

I get 8.8 feet.

2^2 + x^2 = 9^2

4 + x^2 = 81

x^2 = 77

x = 8.77496 to be exact.
