Expert Solution
Step 1

We are required to calculate the reference angle for a. 21π4b. 240°c. 614°d. 17π5

 

 

To calculate the reference angle for a given angle θ we express θ as 

 

θ=180°×n±α  if θ is in degrees provided 0°α<90° and n is an integerorθ=n×π±α if θ is in radians provided 0α<π2 and n is an integer

 

The angle α is then called as the reference angle for the given angle θ.
