Answer: Cos ∠S = 48/73
Explanation:
Triangle QRS is a right angle triangle.
From the given right angle triangle,
RS represents the hypotenuse of the right angle triangle.
With m∠S as the reference angle,
QS represents the adjacent side of the right angle triangle.
QR represents the opposite side of the right angle triangle.
To determine Cos ∠S, we would apply the cosine trigonometric ratio.
Cos θ, = adjacent side/hypotenuse. Therefore,
Cos ∠S = 48/73
