Need help ASAP! Triangles ABC and DEF are similar. Find x?
A.) 9.45
B.) 7.23
C.) 6.12
D.) 8.57

Answer:
D. 8.57
Step-by-step explanation:
Okay I'm not sure if I do these problems correctly, but I always get the right answer.
7/11 = 0.6363...
15/0.6363... = 23.5714...
23.5714...- 15 = 8.57
The value of x would be option D.) 8.57
Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or
[tex]\dfrac{a}{b}[/tex]
Triangles ABC and DEF are similar.
The ratio would be
DE / AB = DF / AC
We know that
15 / 15 + x = 7 / 11
So,
7/11 = 0.6363
15 / 15 + x = 0.6363
By cross multiplication;
15/0.6363 = 15 + x
23.5714 = 15 + x
x = 23.5714 - 15
x = 8.57
