Answer:
7
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the legs is equal to the square of the hypotenuse. If x represents the unknown leg, this means ...
x² +8² = (√113)²
x² = 113 -64 = 49 . . . . subtract 8²
x = √49 = 7 . . . . . . . . take the square root
The length of the other leg is 7.
