one leg of a right triangle measures 12 inches and its hypotenuse measures 15 inches. what is the length of the other leg

9 inches

Step-by-step explanation:

Use the Pythagorean Theorem for this problem

a^2 + b^2 = c^2

We are finding the length of another leg so we change the equation to:

c^2 - a^2 = b^2

c = 15 and a = 12

15^2 - 12^2 = b^2

255 - 144 = 81

Square root the 81 to find that 9 is the answer
