Question

I still need help on this please

Answer 1

x =
`(85)/(3)`

Explanation:

From the figure attached,

ΔABC ~ ΔADE

Therefore, by the property of similar triangles corresponding sides of the given triangles will be proportional.

`(AB)/(AD)=(AC)/(AE)=(BC)/(DE)`

`(AB)/(AD)=(BC)/(DE)`

`(12)/(20)=(17)/(x)`

x =
`(20* 17)/(12)`

x =
`(85)/(3)`
