Sorry if it’s blurry it’s hard to take pictures of a computer screen lol im not very good at this subject in math so all help is appreciated :D

Answer 1

• If they are similar triangles then the ratio AE:BE equals the ratio DE:BC
• The ratio AE:BE can be written as the fraction
  `AE:BE=(AE)/(BE)= (9cm)/(BE)`
• The ratio DE:BC can be written as the fraction
  `DE:BE=(DE)/(BE)=(6cm)/(16cm) =(3)/(8)`
• 
  `AE:BE=DE:BC\\(9cm)/(BE)=(3)/(8) \\BE*3=8*9cm\\BE*3=72cm\\BE=24cm`
