Triangle Q R S is shown. Angle Q R S is a right angle. Angle R S Q is 30 degrees and angle S Q R is 60 degrees. The length of R S is 5 StartRoot 3 EndRoot, the length of S Q is 10, and the length of R Q is 5.
Given right triangle QRS, what is the value of sin(30°)?

StartFraction StartRoot 3 EndRoot Over 3 EndFraction
One-half
StartFraction StartRoot 3 EndRoot Over 2 EndFraction
StartFraction 2 Over 1 EndFraction

sin(30°) = opposite/hypotenuse. For ∠S = 30°, opposite = RQ = 5 and hypotenuse = SQ = 10, so sin(30°) = 5/10 = 1/2.
