Answer:
The exact answer is sqrt(170)
The approximate answer is roughly 13.0384
=======================================
Step-by-step explanation:
We have a right triangle with two known sides. Use the pythagorean theorem to find the third side
Known sides:
a = 7
b = 11
Unknown side is c which is the hypotenuse (longest side)
a^2 + b^2 = c^2
7^2 + 11^2 = c^2
49 + 121 = c^2
170 = c^2
c^2 = 170
c = sqrt(170)
c = 13.0384
Note: the last value is approximate
