Question

In the following figure, two parallel lines l and m are cut by two transversals p and q. Determine the values of x and y.

Answer 1

Since, l || m and q is a transversal.

∴ x = 110°  ...[Alternate interior angles]

Now, l || m and p is a transversal.

∴ y + 80° = 180°  ...[Co-interior angles]

∴ y = 180° – 80° = 100°

Thus, x = 110° and y = 100°
