Question

In the given fig l//m find the unknown angles

Answer 1

7 is 110and 3 is 70 and 6 is70 and2 is110and 4 is 70 and5 is 110and 1 is 70

Answer 2

angle 2 = 110° (vertically opposite angles )
angle 7 = 110° ( corresponding angles )
angle 5 = 110° ( alternate exterior angle )
now, l is a straight line.
so, 110° + angle 1 = 180° ( linear pair )
angle 1 = 180° - 110°
=70°
angle 3 = 70° ( vertically opposite angles )
angle 4 = 70° ( corresponding angle )
angle 6 = 70° ( alternate exterior angle ).
