Answer:

Supplementary

x = 34

Explanation:

  • Supplementary angles: Angles that measure up to 180°
  • Write an equation to find x

4x + 10 + x = 180

  • Group like terms

4x + x + 10 = 180

  • Add: 4x + x = 5x

5x + 10 = 180

  • Subtract 10 from both sides

5x + 10 - 10 = 180 - 10

5x = 170

  • Divide both sides by 5

5x / 5 = 170 / 5

x = 34
The angles are supplementary, which means the angles form a linear pair.
(4x+10)°+x°=180°
5x=170
x=170/5
x=34
