Right triangle abc has its right angle at c. ac=12 and bc=5 . which trigonometric ratios are correct? select each correct answer. cosa=12/13 tana=12/13 tanb=5/12 sinb=12/13 sina=5/13

The answers are:

The explanation is shown below:

1. By definition, when you have a rigth triangle, you can find the sine, cosine and tangent as following:

3. To know the lenght of the hypotenuse you can apply the Pythagorean Theorem:

4. Therefore if AC=12, BC=5 and the right angle is at C, you can substitute values to find the sine, cosine and tangent of A and B:

the answer is d
