Answer 2

You can use the Pythagorean Theorem, which states:
\[a^2 + b^2 = c^2\]Where a and b are legs and c is the hypotenuse. Plug in:
\[5^2 + x^2 = 10^2\]And solve for x.

Answer 3

This is a 30-60-90 triangle. That means that the hypotenuse is the short side multiplied by 2.

Answer 4

It also means that the long leg is the short side multiplied by sqrt3
