I am working on test corrections and don’t get this question 1. For which angle of the triangle is the cosine ratio equal to 15/17

Answer:
For angle A
Explanation:
The cosine of an angle is equal to the adjacent side over the hypotenuse. So, if the cosine is 15/17, the adjacent side is 15 and the hypotenuse is 17. The angle with an adjacent side of 15 is A, therefore
cos(A) = 15/17
So, the answer is angle A.
