Question

In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 8 in.?
8√ in.
2√8 in.
8√2 in.
8√8 in.

Answer 1

In a 45 45 90 triangle, when you known the length of one of the legs the hypotenuse equals the leg times the square root of 2.

So the hypotenuse = 8 * square root of 2 =
8 * 1.4142135624 =
11.313708499
So, the answer is C
