Ok, so what we want to do here is first remove the repeating decimal.
x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating
Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.
100x=216.6 repeating
-10x=21.6 repeating

90x=195
Divide both sides by 90.
x=195/90
Now you can simplify that into 13/6.
Answer:
x =5
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of one triangle over the same side of the other triangle.
x 4
------ = ----------
40 32
Using cross products
32x = 4*40
32x = 160
Divide each side by 32
32x/32 =160/32
x =5
