Answer 1

Answer:

Step-by-step explanation:

Since AB||CD, BC is the transversal.

∠ABC = ∠DCB (Alternate angles)

=> 70° = ∠3.

We know that sum of all angles at ∠C should be 180°

=> 45° + ∠3 + ∠2 = 180°

=> 45° + 70° + ∠2 = 180° (∵ ∠3 = 70°)

=>∠2 = 180  - 115 = 65°.

Now we now that sum of all angles in a triangle is always equal to 180°.

=> ∠1 + ∠2 + 70° = 180°

=> ∠1 + 65° + 70° = 180°  (∵ ∠2 = 65°)

=> ∠1 = 180 - 135 = 45°.

Thus ∠1 = 45°, ∠2 = 65° and ∠3 = 70°
