Largest possible area of the triangle is 27.7128

Given are the two angles #(2pi)/3# and #pi/6# and the length 8

The remaining angle:

#= pi - (((2pi)/3) + pi/6) = pi/6#

I am assuming that length AB (8) is opposite the smallest angle.

Using the ASA

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

Area#=( 8^2*sin(pi/6)*sin((2pi)/3))/(2*sin(pi/6))#

Area#=27.7128#
