Angles 1 and 2 are supplementary.
• The measure of angle 1 is (2x - 3) ◦
• The measure of angle 2 is (-5x + 423) ◦

Answer:

1 = 157°

2 = 23°

Step-by-step explanation:

  • because the angles are supplementary, their angles will add up to 180°
  • set up the equation (2x-3)+(-5x+423)=180
  • combine like terms to get -3x+420=180
  • subtract 420 from 180 to get -3x=-240
  • divide by three and get x=80
  • now plug in 80 for x in both equations
