(2n+4)x(4n+7)
= 8n^2+14x+16n+28
=8n^2+30n+28
that's it :) !!

The big circle has a radius of 4 and the small circle has a radius of 2. You divide the bigger circle by the smaller circle. 4/2=2
Basically, you need to calculate "x" correct?
The tangent of (52) = x / 20
1.2799 = x / 20
x = 1.2799 * 20
