Given ray OC is perpendicular to ray OA and <DOA=135 degrees,what would be the measure of <DOC given that <COB=3x-7 and <BOA= -2x+4.
Answered by Steve
Huh? If the points A,B,C,D are in sequence, then since <AOC = 90,
<DOC = 135-90 = 45

If the angles are in some other order, then you may have to find x first.

I don't quite understand
