Question

Helpp plzzz pt.3 yeahh​

Answer 1

AB = 4.5

Explanation:

We can cross multiply the sides in order to find the length of AB. Make sure you don't go diagonal, so you can't do 3/6. You can do 3/4 and 3/x, then match it to the same pattern.

This is the one I chose...

`(4)/(3) =(6)/(x)`

Notice how I put them in the same order.

Now we can cross multiply...

`4*x`

= 4x

`6*3`

= 18

`4x=18`

Divide by 4.

x = 4.5

The length of AB is 4.5.
