A unit circle. A point is on the circle at (one-half, StartFraction StartRoot 3 EndRoot Over 2 EndFraction) and forms a right triangle with the x-axis. The triangle has side lengths one-half, StartFraction StartRoot 3 EndRoot Over 2 EndFraction, and hypotenuse of 1. The angle formed with the point and x-axis is 60 degrees. Use the diagram shown to answer the question. What are the sine and cosine values of a 60° angle?
sine (60 degrees) = StartFraction StartRoot 3 EndRoot Over 2 EndFraction and cosine (60 degrees) = one-half
Sine (60 degrees) = one-half and cosine (60 degrees) = StartFraction StartRoot 3 EndRoot Over 2 EndFraction
sine (60 degrees) = StartFraction StartRoot 3 EndRoot Over 2 EndFraction and cosine (60 degrees) = 1
Sine (60 degrees) = one-half and cos(60°) = 1
