Question

GOAL is a quadrilateral in which GO is parallel to AL if angleG=angleO=40 then find the measures of angles A and L

Answer 1

x+40 = 180

x = 140

so angle A= angle L = 140

Any doubts comment

Answer 2

Let the angle A and angle L be x

x + 40 =180 ( linear pair )

x = 180 - 40 = 140°

Angle A = 140°

Angle a = angle L= 140°

Hope it will helpful for everyone ☺️
