Question

Find an angle in each quadrant with a common reference angle with 141°, fromDºsO<360°

Answer 1

we have the angle of 141 degrees

the given angle lies on the II quadrant

The reference angle is

180-141=39 degrees

so

Quadrant I ------> 39 degrees

Quadrant II -----> 141 degrees

Quadrant III ---> 180+39=219 degrees

Quadrant IV ----> 360-39=321 degrees
