Question

Please help!
Find the positive and negative angles of smallest magnitude that are coterminal with -240 degrees.
The smallest positive angle is...?

Answer 1

this is like the problem we did earlier

Answer 2

except instead of radians, we are in degrees

Answer 3

the concept is essentially the same, though, you just have to go one rotation around the circle to get to a coterminal angle.

Answer 4

this time instead of adding or subtracting 2pi radians, we are adding or subtracting 360 degrees.

Answer 5

so adding 360 would give you a positive value of 120 that is coterminal.

Answer 6

and subtracting 360 (going back around a full turn) would give us -600

Answer 7

Oh I see. Thank you for the explaining. I see how the two problems are similar.

Answer 8

that is good! you are welcome
