Answer:
x = 14
Step-by-step explanation:
As the triangle was dilated, all its sides increased by the same ratio.
So, as one side was 3 and then increased to 9, the ratio is:
ratio = 9 / 3 = 3
So, using this same ratio for the other side given, we can find the value of x.
The larger side of length x+1 is 3 times greater than the small side of length 5:
x + 1 = 3 * 5
x + 1 = 15
x = 14
