How to find the missing side using pythagorean theorem

Answer 1

Hey there!

To start, the Pythagorean Theorem is a²+b²=c² where a and b are the two legs of a right triangle (the sides that aren't the hypotenuse) and c is the hypotenuse.

In the case you need to find side a, first isolate a² in which you do so by subtracting b² from both sides and finding the square root of both sides:

a² = c²- b²

a = $\sqrt{c^{2}-b^{2} }$

As for finding side b, you do the same:

b² = c² - a²

b = $\sqrt{c^{2}-a^{2} }$

To find side c (the hypotenuse), find the square root of both sides:

c = $\sqrt{a^{2}+b^{2} }$

Hope this helps!
