Question Analysis

The main focus is to determine which trigonometric function is appropriate when the two non - hypotenuse sides of a right - triangle are given. This requires understanding the definitions of sine, cosine, and tangent in terms of the sides of a right - triangle.

Key Concept Explanation

Sine (sin): Defined as . It requires the length of the hypotenuse along with the opposite side to an angle .

Cosine (cos): Defined as . It also requires the length of the hypotenuse along with the adjacent side to an angle .

Tangent (tan): Defined as . This function only needs the lengths of the two non - hypotenuse sides (opposite and adjacent to the angle
