Question

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

Answer 1

Step-by-step explanation:

angle D = 130 degree

z = 130 , adjacent angle to D

x = 50 , linear pair with z

y = 120 , adjacent to 120

t = 120 , vertically opposite to 120

Answer 2

t=120° (vertically opposite angle)

y=120°(alternative interior angle)

x=50(alternative exterior angle)

z=180--50=130°(linear pair)
