Answer 2

What side is the hypotenuse?

Answer 3

10

Answer 4

The hypotenuse is the longest side of the triangle. Therefore, we can eliminate answers C and D.

Answer 5

Are you familiar with the equation a^2+b^2=c^2?

Answer 6

A little!

Answer 7

Well, in this equation, "a" and "b" represent the legs of the triangle. "C" represents the hypotenuse.
We know c, the hypotenuse, is 10.
We also know that a and b are the same length.
So...
\[x ^{2}+x^{2}=10^{2}\]
