Question

I have no clue how to do this

Answer 1

CE = 12

Explanation:

ΔCDB and ΔEAB are similar, hence the ratios of corresponding sides are equal

We require to find the length of BC to complete CE

`(BC)/(BE)` =
`(DB)/(AB)`, substitute values

`(BC)/(8)` =
`(5)/(10)` ( cross- multiply )

10BC = 40 ( divide both sides by 10 )

BC = 4

CE = CB + BE =4 + 8 = 12
