Answer:

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle,

BC represents the hypotenuse of the right angle triangle.

With m∠C as the reference angle,

AC represents the adjacent side of the right angle triangle.

AB represents the opposite side of the right angle triangle. if Sin C = 15/17, it means that

Opposite side = 15

Hypotenuse = 17

We would find the adjacent side by applying Pythagorean theorem. Therefore,

Adjacent side² = 17² - 15² = 64

Adjacent side √ 64 = 8

To determine the ratio of Cos C, we would apply

the cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos C = 8/17
