Find the sine of ∠R.
Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
sin(R) =

Answer

sin(R) is the ratio of the length of the side opposite ∠R to the hypotenuse in the right triangle PQR.

  1. The side opposite ∠R is PQ, which is 12.
  2. The hypotenuse is PR, which is 13.

Therefore, sin(R) = 12/13.
