Answer is Option-D => ∠R
Sinθ Formula:
The sine of an angle of a right-angled triangle is the ratio of its perpendicular (that is opposite to the angle) to the hypotenuse. The sin formula is given as: sinθ = Perpendicular / Hypotenuse
Here, (Given)
Perpendicular = 12
Hypotenuse = 37
So, For sinR, we get 12/37 value as the opposite side of an angle ∠R is 12.
Answer is ∠R.
