Question

Two lines AB and CD intersect each other at point O, The angle ∠AOC= 54 degree and ∠COB= x respectively . What is the value of x ?

Answer 1

Answer:

126°

Step-by-step explanation:

angle AOC and angle COB are on a straight line (given).

then,

Angle AOC + Angle COB = 180° (Linear Pair)

54° + Angle COB = 180°

Angle COB = 180° - 54°

Angle COB = 126°
