The angle ∠2 is a vertically opposite angle to the angle 145°, so they are congruent:
∠2 = 145°
The angles 1 and 3 are supplementary angles to the angle 145°, so they are equal to:
180° - 145° = 35°
∠1 = 35°
∠3 = 35°
The angle 8 is a corresponding angle to the angle 145°, so they are congruent:
∠8 = 145°
The angle ∠6 is a vertically opposite angle to the angle ∠8 so they are congruent:
∠6 = 145°
The angles 5 and 7 are supplementary angles to the angle ∠8, so they are equal to:
180° - 145° = 35°
∠5 = 35°
∠7 = 35°
