Answer:

X= 7 units

Step-by-step explanation:

since the triangles are similar the ratio. of their common sides will be equal so,

BE/BD= BC/BA

(4X-8)/18= 45/22.5

4X -8 = 18×2

4X= 36-8

X= 28/4

X= 7
  • BD/AB=BE/BC
  • 18/18+22.5=4x-8/45
  • 18/40.5=4x-8/45
  • 40.5(4x-8)=810
  • 4x-8=20
  • 4x=28
  • x=7
