Step-by-step explanation:
Two parallel lines are cut by a transversal. So the alternate interior and exterior angles are equal as shown in the diagram.
- Here angle 1 = 4 = 5 = 8
- angle 2 = 3 = 6 = 7
In the first figure, the value of the angle adjacent to x is 110 degree. So
- x = 180 - 110
- x = 70 degree
In the second figure, due to vertical opposite angles x = 80 degrees.
