Question

A right triangle has a leg length of 21 inches and a hypotenuse length of 29 inches. What is the length of the other leg?​

Answer 1

20

Explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

21^2 + b^2 = 29^2

441 + b^2 = 841

Subtract 441 on both sides to get b^2 = 400

Take the square root of both sides to get b = 20
