Given the reference angle of start fraction, 2, pi, divided by, 9, end fraction 92π , find the corresponding angle in Quadrant 22.
Question
Given the reference angle of start fraction, 2, pi, divided by, 9, end fraction 92π , find the corresponding angle in Quadrant 22.
Solution
The reference angle given is 2π/9. This is an angle in the first quadrant.
To find the corresponding angle in the second quadrant, we subtract the reference angle from π (or 180 degrees).
So, the corresponding angle in the second quadrant is π - 2π/9 = 7π/9.
