Question

find the missing sides.round to the nearest tenth.pls answer quickly i really dont know the answer and i need help fast​

Answer 1

x=7.7 units

y=11.1 units

Explanation:

This problem uses ratios of similar triangles to find the missing sides of the triangle. You need to compare similar sides of the triangle to find the missing sides.

`(18)/(28) =(x)/(12)`

`(18)(12)=28x`

`216=28x`

`216/28=28x/28`

`7.7=x`

Therefore x=7.7 units

Next, we need to solve for Y.

`(18)/(28) =(20)/(y+20)`

`18(y+20)=(28)(20)`

`18y+360=560`

`18y+360-360=560-360`

`18y=200`

`18y/18=200/18`

`y=11.1`

Therefore y=11.1 units
