Answer:
The measure of angle θ is 7π/6. The measure of its reference angle is 210°
and sin θ is -1/2.
Step-by-step explanation:
The correct question is:
The measure of angle θ is 7π/6. The measure of its reference angle is ___
and sin θ is ___
180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:
180° / π radians = x° / (7π/6 radians)
x = (180/π) * (7π/6 radians)
x = 210°
And sin(210°) = -1/2
