The smaller triangle was dilated to form the larger triangle. What is the value of x?
strojnjashka [21]

Answer:

The value of x is 14

Step-by-step explanation:

The value of x is 14 because the smaller triangle was dilated by 3 to get the bigger triangle. I figured this out because

9 ÷ 3 = 3

so this would mean that 5 was dilated by 3 also. So to figure this out, it would be

5 × 3 = 15

1 of that 15 is already there.

So this means that

15-1=14

A=14

I hope this helps you.
