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.) PLEASE USE RATIOS NOT COSINE AND PLEASE PLEASE PLEEEEEAAAAAAAAAASE SHOW YOUR REASONING AND WORK! Triangle ABC: AB = 63, AC = 16, CB (hypotenuse thing) = 65
