Question

In the given figure, AB is parallel CD and AD, BC are the transversals. The measure of angle AOB is​

Answer 1

Answer:

angle AOB = 75°

Step-by-step explanation:

In triangle OCD

= angleC + angleD+ angleO = 180° (Angle Sum Property)

= 45° + 60° + angleO = 180°

= 105° + angleO = 180°

= angleO = 180°- 105°

= angleO = 75°

= angle COD = angle AOB (Vertically opposite angle)

= angle AOB = 75°
