Question 344506
To find coterminal angles (which are measured in degrees) just add (or subtract) 360 degrees. Since your starting angle, -400, is less than all the proposed answers, just keep adding 360's until you get one of the answers provided.<br>
To get you started:
-400 + 360 = -40
This is not one of the possible solutions. So next we add 360 to -40. Continue this until you get one of the proposed solutions.
