How do you find the complement angle and the cofunction of that complement of cos241 degrees?

Question

Show that they equal each other.

Answer 1

that's very close to cos240 which is 60 degrees more than 180 degrees

cos240 = -1/2

the complement angle is the angle that adds to the angle to get 90 degrees.

60 + 30 = 90. You probably want 30 degrees more than 180 or 210 degrees. It has cos210 = -1/sqr3

but you had 241, so it's all a little off, but not by much.
