Answer:
65.
You would have to use the Pythagorean theorem in order to find the Hypotenuse (Side that is missing)
Explanation:
The equation is:
C = a^2 + b^2 - square root of the answer.
So it would be set up like this.
56^2 = 3136
33^2 = 1089
1089 + 3136 = 4225.
The square root of 4225 is 65.
Thus, 65 is the answer.
Hope this helps!
