We need a picture of the shape.
A=P(1+r%)ⁿ , where P is the initial capital, r, the interest rate and n, the # years
A = 2000(1+0.13)³
A = 2000(1.13)³
A = 2,885.79
The angle should not change. 35 degrees
In general, any equation like
(assuming
) is solved by

So, in your case, the solution is

Dividing by a fraction means to multiply by the inverse of that fraction:
