The legs of a right triangle measures 9ft and 12ft. What is the length of the hypotenuse

The hypotenuse would be 15ft

Step-by-step explanation:

You would use pythagorean theorum which would make the equation 9²+12²=c²

next step would be to make it √81+144=c²

then you would get √225=c²

then you just calculate the square root of 225 and you have your answer.

answer: .64
