In this video, we are going to look at how to find a missing side length of a right triangle by using the Pythagorean Theorem.
where a and b are lengths of legs of the right triangle,
and c is the length of the hypotenuse.
To solve the following equation:
Substitute the variables where 3 replaces a and 4 replaces b
Solve for and
Add the 9 and the 16 together, leaving us with:
Find the square roots on both sides
Leaving us with:
So the hypotenuse equals to 5
