3. one method you can use to determine whether a triangle is a right triangle, given three side lengths, is to apply the converse of the pythagorean theorem. alternately, you can use trigonometric ratios. show that the triangle in the diagram is a right triangle by using trigonometric ratios. (be sure to show all work and/or reasoning.) use ratios not cosine and plse show your reasoning and work!

triangle abc:
ab = 63, ac = 16, cb (hypotenuse thing) = 65
