PLZ HELP ASAP LAST SIMMILAR TRIANGLES

Answer 1

Remember that in similar triangles the corresponding sides are proportional. Knowing this, we can establish a proportion between sides AD and AB, and between sides ED and CB.

`(AD)/(AB) = (ED)/(CB)`

`(AD)/(2) = (1)/(x)`
Notice that AD=2+1=3, so:

`(3)/(2) = (1)/(x)`
Solving for
`x`:

`x= (2)/(3)`

We can conclude that the value of
`x` is
`(2)/(3)`
