Question

in the given figure, l // m, angle 1 = 78 degree . then find the value of the angle 2

Answer 1

78 degree itself as the l//m

Answer 2

Angle 1 = angle 3 = 78 (corresponding angles are equal)

Angle 3 + angle 2 = 180° ( linear pair line)

78° + angle 2 = 180

angle 2 = 180-78

= 102°

Hence angle 2 is 102°
