Answer:
See below in bold.
Step-by-step explanation:
To do these we add or subtract 360 degrees or 2 pi radians. Sometimes multiple actions are required.
11. Adding 360 to -545:
= -185
185 + 360 = 175
The other angle is 185 degrees so they are not coterminal.
12. 161pi/36 - 2pi
= 161pi /36 - 72pi/36
= 89pi/36
89pi/36 - 72pi/36
= 17pi/36.
So these are coterminal.
13. -330 + 360 = 30 degrees.
14. -435 + 360
= -75
-75 + 360
= 285 degrees
15. 640 - 360 = 280 degrees.
16. -442 + 360 = -82
-82 + 360 = 278 degrees.
Hey!
Hope this helps...
