Answer:

  • x = 2

Explanation:

Use segment addition postulate:

  • SU = ST + TU

Substitute the values from the diagram:

  • ST = 2x + 2
  • TU = 2
  • SU = 5x - 2

Set up and solve the equation for x:

  • 5x - 2 = 2x + 2 + 2
  • 5x - 2 = 2x + 4
  • 5x - 2x = 4 + 2
  • 3x = 6
  • x = 6/3
  • x = 2
