score: 1/20 1/20 answered
question 2
the reference angle of 241° is
the reference angle of 340° is
the reference angle of -166° is

Explanation:

Step1: Find reference angle of 241°

241° is in third quadrant: $241^\circ - 180^\circ = 61^\circ$

Step2: Find reference angle of 340°

340° is in fourth quadrant: $360^\circ - 340^\circ = 20^\circ$

Step3: Find reference angle of -166°

Convert to positive: $360^\circ - 166^\circ = 194^\circ$ (third quadrant), then $194^\circ - 180^\circ = 14^\circ$
