Question Analysis

The core of this question lies in identifying the types of the two given sides of a right - triangle with respect to the angle . This understanding is fundamental for applying trigonometric ratios such as sine, cosine, and tangent.

Key Concept Explanation

Opposite side: In a right - triangle, it refers to the side that is directly opposite the angle of interest, which is  in this case.

Adjacent side: It is the side that is adjacent to the angle  and is not the hypotenuse.

Hypotenuse: The longest side of a right - triangle, which is opposite the right angle.

Step - by - Step Solution

1. Identify the opposite side:

The side with a length of 15 is directly opposite the angle
