Question

In the figure, line / || line m and line n is the transversal, if LABC= aº and LBFG 50° then the value of a is
A)50° B)40° C)150° D)130°​

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
