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
