Question

A Tick) the correct option: 1. If! Ilm, and n is a transversal and B = 60°, then 2 y =? (a) 60° (b) 120 (c) 300 ​

Answer 1

Answer:

Given:l∥m

sum of the interior angles on the same side of transversal is 180

∘

b+52

∘

=180

∘

⇒b=180

∘

−52

∘

=128

∘

And a=52

∘

∴a=52

∘

,b=128
