Answer:

Step-by-step explanation:

∠1 + ∠2 = 180                      Linear pair

∠4 + ∠5 +∠ 3 = 180             form straight line

∠1 + ∠2 = ∠4 + ∠5 + ∠3        from statement 1 and 2

∠3 +∠2 = ∠4 + ∠5 + ∠3          ∠1 and ∠3 are vertically opposite angles.

∠2 = ∠4 + ∠5                           Proved
