Question

In the figure 10.11,l|| m || n. Find angle x and angle y​

Answer 1

Answer:

This is answer is as true A.F.

Answer 2

Answer:

angle x = angle BCX = 30degree (alternate interior angles)

(n||m)

angles LAB=angleL=50degree (alternate interior angles)

Now,

angle Y + angle L =180degrees (linear pair )

angles Y = 180 degrees -50 degree

y=130 degree
