Question

In ΔSTU, the measure of ∠U=90°, TS = 65, UT = 56, and SU = 33. What ratio represents the cosine of ∠S?

Answer 1

33/65

Explanation:

Given the following

∠U=90°,

TS = 65 = HYpotenuse

UT = 56 = Opposite

SU = 33 = Adjacent

Cos <S = adj/hyp

Cos <S = SU/TS

Cos <S = 33/65

Hence the required ratio is 33/65
