This is what I got 53 degrees and 37 degrees are the approximate measures of the angles of a 3-4-5 right triangle. The legs have lengths 3 and 4, and the hypotenuse is 5. The 4 is opposite the larger angle (53 degrees) and the 3 is opposite the 37 degree angle. sin(53) = opposite/hypotenuse = 4/5 sin(37) = opposite/hypotenuse = 3/5 So I think it is C.
