Let the shortest length of the composite plane shape be 1 unit.


(1/sin12) = (a/sin153)

a = 2.18357369878 units.


(2.18357369878/sin27) = (b/sin99)

b = 4.75051853365 units.


c² = 4.75051853365+1-2*4.75051853365cos39

c = 4.02290116111 units.


Calculating the required angle x.

(4.02290116111/sin39) = (1/sinx)

x = 9°
