In the figure below, AC || DE, BD measures 8 m, AD measures 12 m, and BE measures 6 m. Find the length of BC.

In the figure below AC DE BD measures 8 m AD measures 12 m and BE measures 6 m Find the length of BC class=

Answer:

  • BC = 15 units

===============

Parallel lines divide the transversal into proportional segments.

Set ratios and find the missing length

  • BD/AD = BE/ED
  • 8/12 = 6/ED
  • 2/3 = 6 / ED
  • ED = 6*3/2
  • ED = 9

Find BC

  • BC = BE + ED
  • BC = 6 + 9
  • BC = 15
