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