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