This can be solved by systems of linear equations. This problem asked us to find values for brand A and B. As a rule of thumb, the number of unknowns must equal to the number of independent equations. First equation is A = B +43billion and the second is A + B = 109billion. Solve these equation simultaneously you should get:
A=76 billion
B = 33 billion.

Answer: sqrt(3)</h3>
========================================================
Work Shown:
The tangent ratio involves the opposite over adjacent.
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = sqrt(75)/5
tan(A) = ( 5*sqrt(3) )/5 .... see the section below
tan(A) = sqrt(3)
---------------------------
sqrt(75) = sqrt(25*3)
sqrt(75) = sqrt(25)*sqrt(3)
sqrt(75) = 5*sqrt(3)
Tip = 15% of $163.56 = 0.15 x 163.56 = $24.53
