As we know that remote exterior angle can be given by
m<z=m<x+m<y
151-5n=4n-18+n+9
151+18-9=5n+4n+n
160=10n
n=16
m<z=151-5*16
m<z=151-80=71
Answer/Step-by-step explanation:
∆ABC is similar to ∆CDE. Therefore, the ratio of their corresponding sides are proportional.
This,


Solve for x






Use the value of x to find AC and DC
