Question

Help me please I’m losted

Answer 1

`(50)/(3)`

Explanation:

Similar shapes have corresponding sides that are proportional.

So 20 corresponds to x (big to small).

So 12 corresponds to 10 (big to small).

Your information is already lined up for you to setup your proportion:

`(20)/(12)=(x)/(10)`

Cross multiply:

`20(10)=12(x)`

Simplify both sides:

`200=12x`

Divide both sides by 12:

`(200)/(12)=x`

Simplify by dividing top and bottom by 4:

`(50)/(3)=x`
