triangle.
X
7
X =
11
√[?]
PLEASE HELP

Answer 1

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

HOPE THIS HELPS!

Answer 2

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.
