Find the unknown length in the right triangle. If necessary, approximate the length to the nearest thousandth. A: 13in and B: 20in C:?

C creo que es la respuesta

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
