Question

In each of the following figures AB||CD. Find the unknown angles, giving reasons.​

Answer 1

Step-by-step explanation:

t = 180 - 100 (co-interior angles)

= 80

y = 120 (vertically opposite angles are equal)

yfd = 180 - 120 (co-interior angles)

= 60

z = 60 (vertically opposite angles are equal)

Answer 2

Answer:

y=120° (Vertically Opposite Angles)

x= 180°-100°=80° (Adjacent Angles)

z= 60° (Corresponding Angles)

t= x= 80° (Alternate Angles)
