The two legs of a right triangle are 5 ft and 12 ft. How long is the hypotenuse?
Let the hypotenuse be c ft.
a2 + b2 = c2
122 + 52 = c2
144 + 25 = c2
169 = c2
13 ft = c
Using the Pythagorean theorem, one can determine the value of the unknown side of a right
triangle when given the value of the other two sides.
Given that the hypotenuse of a right triangle is 18" and the length of one side is 11",
what is the length of the other side?
