{x}^(2) = 11^(2) + {7}^(2) \\ x = √(121 + 49) \\ x = √(170) \\

HOPE THIS HELPS!

Answer: 170

=====================================================

Step-by-step explanation:

Use the pythagorean theorem to find the hypotenuse.


a^2+b^2 = c^2\\\\c = √(a^2+b^2)\\\\c = √(7^2+11^2)\\\\c = √(49+121)\\\\c = √(170)\\\\

The hypotenuse is exactly
√(170) units long

This is approximately 13.038 units

In other words,
√(170) \approx 13.038 when using your calculator.

So that's why you would type 170 into the green box.
