Question

Suppose a right triangle has a

hypotenuse length of 12. If one of
the legs has length 5, what would
the length of the last leg be?

Answer 1

See the last two lines below. I don't know which one you want.

Explanation:

hypotenuse = 12

One leg = 5

other leg = x Substitute into a^2 + b^2 = c^2

x ^2 + 5^2 = 12^2

x^2 + 25 = 144 Subtract 25 from both sides

x^2 = 144 - 25 Combine

x^2 = 119 Take the square root of both sides

x = sqrt(119)

x = 10.91
