Question

4. Determine the positive and negative co-terminal angle for the given angle:a. 65°b. -125°

Answer 1

Remember that

In order to find a coterminal angle or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible

Part a

we have

65 degrees

so

65+360=425 degrees

65-360=-295 degrees

Part B

we have

-125 degrees

so

-125+360=235 degrees

-125-360=-485 degrees
