Answer:

  1. Angle 1 = 139°
  2. Angle 2 = 41°
  3. x = 29; exterior angle = 131°

Step-by-step explanation:

These problems let you make use of the fact that the sum of the remote interior angles is equal to the exterior angle.

__

1. 53° +86° = ∠1

  139° = ∠1

__

2. ∠2 +92° = 133°

  ∠2 = 133° -92°

  ∠2 = 41°

__

3. (x +9)° +93° = (4x+15)°

  87 = 3x . . . . . . . . . . . . . . . . subtract x+15°

  29 = x . . . . . . . divide by 3

The exterior angle is ...

  (4x +15)° = (4·29 +15)° = 131° . . . exterior angle
