Answer 1

Answer:

As Ray OC is straight then it will be perpendicular on AB . then the whole 180 degree angle is divided into two equal parts so angleAOC=angleCOB=90degree.

Answer 2

Explanation:

ab or aob = 180

aoc = cob ( given )

Aoc + Cob = aob

2 aoc( cause aoc = cob ) = aob

2 aoc = 180 (given)

aoc = 180/2

aoc = 90
