If a right triangle has side lengths of 9 and 12, how long is the hypotenuse?(1 point)

1 answer

To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Therefore, in this case, the hypotenuse^2 = 9^2 + 12^2;
The hypotenuse^2 = 81 + 144;
The hypotenuse^2 = 225.

To find the length of the hypotenuse, you need to take the square root of both sides: hypotenuse = sqrt(225) = 15.

Therefore, the length of the hypotenuse is 15.
