Answer:
A. 7π/6.
Step-by-step explanation:
I think you mean a sine of -1/2 and cosine of -√3/2 ( the values in the question are not possible)
Angle π/6 has a sine of 1/2 and a cosine of √3/2 ( from the 30-60-90 triangle).
This angle must be in the third quadrant because the sin and cos are negative.
So the answer is π +π/6 = 7π/6.
The angle 7π/6 has a sine of −12 and a cosine of −3√2.
What is the sin angle?
The sine of an angle is a function that relates to the sides of a right triangle.
The angle has a sine of −1/2 and a cosine of −3/√2.
Angle π/6 has a sine of 1/2 and a cosine of √3/2 ( from the 30-60-90 triangle).
This angle must be in the third quadrant because the sin and cos are negative.
So the answer is π +π/6 = 7π/6.
Hence, the angle 7π/6 has a sine of −12 and a cosine of −3√2.
