The measure of angle θ 7pi/6 is . the measure of its reference angle is °, and sin θ is

We shall break the given angle into rotation and an angle

is

Also lies in quadrant 3.

In quadrant 3 sin is negative

So

Hence the reference angle of 7π/6 is π/6 and sin (7π/6) = -1/2.

no, because the sides are not congruent
