Question

Which trigonimetric function would you use to solve the problem?

If S=27º and TR=7, find TS

Answer 1

B.

Explanation:

sin or csc

Answer 2

The correct answer is option b. Sin or csc

Explanation:

Trigonometric ratios

Sinθ = Opposite side/Hypotenuse, Cosec = 1/Sinθ

Cosθ = Opposite side/Hypotenuse , Secθ = 1/cosθ

Tan θ = Opposite side/Adjacent side, cotθ = 1/Tan θ

From the figure we can see a right angled triangle RST,

Right angled at R

To find the value of TS

We have m< S=27º and TR=7

Sin S = TR/TS

TS = Sin S * TR

Cosec = 1/Sinθ

Therefore the correct answer is option b
