Question

in the adjoining figure , a transversal r cuts two parallel lines p and q at two points A and B respectively. if angle 1 is 50° find all other angle​

Answer 1

let the angle 1 be x, and the angle in front of angle x be y.

Given....

Angle x=50

Angle y=?

To find the measure of angle y,

Angle x +Angle y=180

50+Angle y=180

Angle y=180-50

Angle y =130

....Therefore the measure of angle y i.e the other angle is 130 by interior angles theorem.
