Question

What is the length of the unknown leg in the right triangle?

Answer 1

Solve by using the formula: c² - b² = a²

c = hypotenuse, b = leg, a = a

Plug in:

(√73)² - (8)² = a²

Simplify.

73 - 64 = a²

9 = a²

Isolate the a. Root both sides

√a² = √9

a = √9

a = √9 = √(3 * 3)

a = 3

3 ft is your answer
