Answer:
5/8, 1/2, 1/6
Step-by-step explanation:
When tan theta = 1 theta = 45 degrees in the first quadrant.
When its = -1 one value of theta is -45 degrees.
Also as the tangent is negative in the second quadrant theta can also be 135 degrees or - 225 degrees.
in fourth quadrant we have 315 degrees.
Its not 225 degrees because the tangent is positive in 3rd quadrant.
Correct answer is a, b, c and e.
