Given two adjacent angles AOB and BOC. The sum of measure of them is equal to 160o and the measure of angle AOB is equal to 7 times the measure of angle BOC
a)Find the measure of each angle
b)Inside angle AOC, draw ray OD such that angle COD=90o. Prove that OD is the bisector of angle BOA.
c)Draw the opposite ray OC' of ray OC. Find the measure of 2 angles AOC and BOC' then compare them
