I don't really know how to explain this but I know my answer is correct.
The smallest angle is 16
The medium size angle is 32
The largest angle is 132
If we let S, M, and L be variables, we can make the following equations
S = 1/2 M
M = 2 S
L = 8 S + 4
L + M + S = 180
If you plug in 16 for S, everything falls into place
