The measure θ of an angle in standard position is given. Find the exact values of cos θ and sin θ for the angle measure:

sin(2pi/3) = sqrt(3)/2

cos(2pi/3) = -1/2

Step-by-step explanation:

2pi/3 lies in the second quadrant with basic angle: pi - 2pi/3 = pi/3

sin(pi/3) = sqrt(3)/2

cos(pi/3) = 1/2

In the second quadrant, sin is positive and cos is negative

Therefore,

sin(2pi/3) = sqrt(3)/2

cos(2pi/3) = -1/2

the answer is 9 because the question is telling how much it be together.

your answer is #3 , 8 - 3 square root of 11
