Answer:
x = 3.2
Step-by-step explanation:
Because they are similar, the second shape is just a dilation of the first. Because of this, you need to find the scale in which it is dilated.
To do this we would do the following:
(Taking the lengths of the bigger shape divided by the smaller one.)
3 ÷ 2.4 = 1.25
5 ÷ 4 = 1.25
This tells us that the second shape is dilated by a scale of 1.25. Now all we have to do is multiply 4 by this scale to get x.
It looks like this:
4 × 1.25 = 3.2
I hope this helped :)
