solve it fast pls.....​

Answer 1

Answer:

Step-by-step explanation:

As AB//CD and CD //EF

Therefore, AB//CD//EF.

Angle X= angle Z (alternate interior angles are equal.

Angle X + angle Y = 180 degrees (sum of same side of transverse)

Ratio of angle Y : angle Z = 3 : 7

This is equal to ratio of angle Y : angle X

Therefore, Angle X = angle Z = (7/10) x 180

= 126 degrees.

And angle Y = (3/10) x 180= 54 degrees.
