Use Pythagorean theorem a^2 + b^2 = c^2
13^2 + 20^2 = c^2
169 + 400 = c^2
569 = c^2 Use square root property to get c by itself. So you find the square root of both sides
23.853 = c
13^2 + 20^2 = c^2
169 + 400 = c^2
569 = c^2 Use square root property to get c by itself. So you find the square root of both sides
23.853 = c
