Given the reference angle of start fraction, pi, divided by, 5, end fraction 5π , find the corresponding angle in Quadrant 22.
Question
Given the reference angle of start fraction, pi, divided by, 5, end fraction 5π , find the corresponding angle in Quadrant 22.
Solution
The reference angle given is π/5. This is the angle made with the x-axis in the positive direction.
In Quadrant II, angles range from π to 2π.
The corresponding angle in Quadrant II would be π - (π/5) = 4π/5.
So, the corresponding angle in Quadrant II for the reference angle π/5 is 4π/5.
