Answer 2

First complete the triangle ONM. Sides ON = OM, so angle OMN = angle ONM = 33 degrees. If the two angles are 33 degrees then what is the third angle of the triangle?

Answer 3

okay well u see this

Answer 4

there is a neat identity that say this angle from the center to this point is 2* the angle at the edge of the circle

Answer 5

This is the completed triangle ONM. In it you know that two angles are 33 degrees and you have to find the third angle:

Answer 6

remember there are 360 degrees in a 1 full rotation so 1 straight line is 180

Answer 7

got that..
