Question

If angle 4=100 then of angle 6

Answer 1

Angles 6=80°

As angle 4 + angle 6=180°

=》100+angle 6=180°

So,Angle 6=180-100=80°

Answer 2

Hey Mate!!

Angle 4 = 100°

According to Transversal cutting through two parallel lines theory ;

Angle 4 = Angle 6 ( ∵ Alternative Angles are equal)

So, Angle 6 = 100°

If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent.

Hope this helps you!!
