Question

For the following right triangle, find the side length X. Round your answer to the nearest hundredth

Answer 1

x = 7.48

Explanation:

You need to use the Pythagorean theorem to solve this problem.

leg^2 + leg^2 = hypotenuse^2

a^2 + b^2 = c^2

5^2 + x^2 = 9^2

25 + x^2 = 81

subtract 25 from both sides.

x^2 = 81 - 25

x^2 = 56

Square root both sides.

x = sqroot(56)

x = 7.48
