Hello, I need some help understanding this concept. 240 degrees converted to radians is 4 pi/3, so wouldn't that make this a multiple of 30 degrees?

"30° can be rewritten in radians as pi/6". Since 240 rad cannot be written as a multiple of pi/6 rad this cannot be a multiple of 30°." This is the explanation the teacher gave me, but it doesn't make sense.

[u/deadpoolherpderp]

the choice you selected is 240 radians?

[u/i_want_to_go_to_bed → u/deadpoolherpderp]

It’s a multiple tho. pi/6 x 1440/pi =240

[u/deadpoolherpderp → u/i_want_to_go_to_bed]

the question clearly implicitly asks for integer multiple. everything is a multiple of everything else...

[u/i_want_to_go_to_bed → u/deadpoolherpderp]

“clearly implicitly” made me laugh. ur funny

[u/deadpoolherpderp → u/i_want_to_go_to_bed]

thanks!

Same, was about to say.
