Question

if ray OC stands on line AB such that angle AOC =angle COB,then find angle AOC.​

Answer 1

AB is a straight line in which OC is standing means OC is perpendicular To AB. SoOF perpendicular to AB then, O is the M.p of AB, AngLe BOC=Angle AOC BOC=90 degree because it is perpendicular to AB. Boc+Aoc=180 (linear pair).

Answer 2

Answer:

90

Step-by-step explanation:

Angle AOC=Angle COB—(1)

Angle AOC+angle COB=180(linear pair)

From (1)we get:Angle AOC×2=180

Angle AOC=180÷2=90
