Answer:
The correct answer is option b. Sin or csc
Step-by-step explanation:
<u>Trigonometric ratios</u>
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
<u> To find the value of TS</u>
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
0,1,2 is the correct answer
If all need to have a common denominator;
1/2 = 6/12
3/4 = 9/12
4/6 = 8/12
So if my ans was helpful u can follow me.
