Pythagorean Theorem

In this topic, we use simple exponents.
To review exponent basics, see here.

The Pythagorean Theorem states that for a right triangle,
a2 + b2 = c 2
where a and b are the lengths of the legs and c is the length of the hypotenuse.
The hypotenuse is the longest side on a right triangle and the side that is opposite of the right angle.

Example 1:

Find the value of 'x' using the Pythagorean Theorem.

We use the Pythagorean Theorem to solve for 'x'.
The hypotenuse has a length of 13.
a2 + b2 = c2
122 + x2 = 132
144 + x2 = 169
x2 = 169 - 144
x2 = 25
x = 5
