150 degrees and 180 degrees

• pre calc -

360 degrees is 2 pi radians

Therefore 180 degrees is pi radians

150 degrees is 5/6 of that.

Multiply degrees by pi/180 to get radians.

• pre calc -

so 150 degrees is 5 pi/6
and 180 degrees = pi

• pre calc -

Yes

• pre calc -

is 270 degreees equal to 3 pi/2

• pre calc -

Yes again
