Answer 1

Answer:

Step-by-step explanation:

1) ∠1 + 31 +69 = 180   {Angle sum property of triangle}

∠1 + 100 = 180

∠1 = 180 -100

∠1 = 80

2) Exterior angle equals the sum of opposite interior angles.

∠2 + 45 = ∠1

∠2 + 45 = 80

∠2 = 80 - 45

∠2 = 35

3)Exterior angle equals the sum of opposite interior angles.

∠3 + 47 = ∠1

∠3 + 47 = 80

∠3 = 80 - 47

∠3 = 33
