Question

For the following right triangle, find the side length x.
A = 40
X
B = 9

Answer 1

They answer is or should be 41

Answer 2

41

Explanation:

Use the Pythagorean Theorem to find the hypotenuse.

`a^(2) +b^(2) =c^(2)`

Plug in the values.

`40^(2) +9^(2) =c^(2)`

Simplify.

`1600+81=c^(2)`

Add.

`1681=c^(2)`

Take the square root of both sides.

`√(1681)=\sqrt{ c^(2)`

41=c
