Answer;
Sin θ = 3/5
Explanation;
Sine is a trigonometric ratio that is given by the ratio of opposite to hypotenuse.
In this case, the opposite is to angle θ is 3 and the hypotenuse is 5
Therefore; sine θ =3/5
The correct choice is (B) Sinθ = 3/5
According to the trigonometric ratios
Sinθ = Perpendicular / Hypotenuse
If we put the values
Sinθ = 3 / 5
which satisfies option B
