Question

8.
Find the measures of all the angles in the following
figure. Given that a is parallel to b.​

Answer 1

Answer:

Angle 3 = 25 degree (vertically opposite angles)

Angle 4 = 180 degree - 25 degree

             = 155 degree (linear pair)

Angle 2 = Angle 4 = 155 degree (vertically opposite angles)

Angle 5 = Angle 2 = 155 degree (Alternate interior angles)

Angle 8 = Angle 3 = 25 degree (Alternate interior angles)

Angle 6 = Angle 8 = 25 degree (vertically opposite angles)

Angle 7 = Angle 5 = 155 degree (vertically opposite angles)
