What is the measure of angle BOC A 79 degrees B 35 degrees C 66 degrees D 114 degrees

Answer :

c. 66 degrees. A straight line has an angle of 180 degrees. Angle AOB, BOC’, and C’OA’ add to 180 degrees. Thus, subtract 79 degrees and 35 degrees from 180, and you will get 66 degrees, the measure of angle BOC’
