Largest possible area = 0.683

Given are the two angles #(7pi)/12# and #pi/4# and the length 1

The remaining angle:

#= pi - (((7pi)/12) + pi/4) = pi/6#

I am assuming that length AB (1) is opposite the smallest angle.

Using the ASA

Area#=(c^2*sin(A)*sin(B))/(2*sin(C)#

Area#=( 1^2*sin(pi/4)*sin((7pi)/12))/(2*sin(pi/6))#

Area#=0.683
