Answer:

  • CD = 6.3

Step-by-step explanation:

The triangles CED and CGF are similar since two sides are on same line and one side is parallel.

Corresponding sides have equal ratios:

  • CG/CE = CF/CD
  • CG/CE = (CD - 1.8)/CD
  • 6/(6 + 2.4) = (CD - 1.8)/CD
  • 6/8.4 = (CD - 1.8)/CD
  • 1/1.4 = (CD - 1.8)/CD
  • 1*CD = 1.4CD - 1.4*1.8
  • 0.4CD = 2.52
  • CD = 2.52/0.4
  • CD = 6.3
