Answer:
A) 12
Step-by-step explanation:
Since triangles YRZ and QRS are similar by AA, the ratio of their sides should be constant. Since RY=QY, let's call that side length y.

Multiply both sides by 2y:

Hope this helps!
Answer:
Y = 5
Step-by-step explanation:
RT = RS + ST
44 = 4y + 2 + 3y + 7
44 -2 -7 = 7y
35 = 7y
y = 5
By solving this problem, I got D.-8.Right?
The answer is 46.44 because if you multiply 9 by 5.16 you can easily find out that it is 46.44
