Question Analysis

The main focus of this question is to determine the appropriate trigonometric ratio among csc, sec, and cot to find the unknown side  in a right - triangle, given that 25 is the adjacent side and  is the opposite side to the  angle. It requires understanding the definitions of these trigonometric functions.

Key Concept Explanation

Cosecant (csc):

Secant (sec):

Cotangent (cot):
