Question

Pls help me fast pls

Answer 1

Answer:

proved

Step-by-step explanation:

ABC=100°......,(ASP)

FBC=80°........(angles on straight line)

l//m

as conjugate angles are equal

Answer 2

Step-by-step explanation__________

∠A+ ∠B+ ∠C = 180         (angle sum property)

Therefore, 45° +35°+∠B= 180

                  80+∠B=180

          ∠B=100°

So, ∠B=∠B      (vertically opp. angles are equal)

      Hence,,, ∠DBF = 100°

So,

    By converse of co-interior angle axiom, ∠D+∠B

                                                                        80+100=180

And if the co-interior angles are equal,, by Converse Of Co-Interior Axiom,

              p║m

Hence, proved.
