Rate of growing, r = 91.2/90 = 1.013
Salary, f(x) = Initial salary * (r)^ (years from 2005)
f(x) = 90(1.013)^x.
This is the second option.
I think you'd use the pythagoran theorem for this (a squared + b squared = c squared). So 30 squared plus 22 squared equals the diagonal measure squared. This is 900 + 484 = c squared. That's 1384. The square root of that is 37.
Since it's a rhombus, all the sides are equal.
![x + 2 = 3x \\ 3x - x = 2 \\ 2x = 2 \\ x = 1](https://tex.z-dn.net/?f=x%20%2B%202%20%3D%203x%20%5C%5C%203x%20-%20x%20%3D%202%20%5C%5C%202x%20%3D%202%20%5C%5C%20x%20%3D%201)
Answer : x = 1
