Which trigonimetric function would you use to solve the problem?

if s=27º and tr=7, find ts

The correct answer is option b.   Sin or csc

Step-by-step 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
