Answer: ∠1= 53°
∠3, ∠6, ∠7 are all 127°
∠4,∠5,∠8 are all 53°
Step-by-step explanation: 127° and ∠1 are supplementary angles meaning they add up to 180° You subtract 127° from 180° to get 53°.
∠3 and 127°are vertical which makes them equal and both 127°.
∠4 is vertical to ∠1 which makes them equal and both 53°.
∠5 is corresponding to ∠1 so they are equal and both 53°.
∠6 is corresponding to 127° so they are equal and both 127°.
∠7 is vertical to ∠6 so they are equal and both 127°.
∠8 is vertical to ∠5 so they are equal and both 53°.
