A triangle has two corners with angles of (3 pi ) / 4 3π4 and ( pi )/ 12 π12. If one side of the triangle has a length of 2 2, what is the largest possible area of the triangle?

Largest possible area of the Delta = color (purple)(2.7321)

Explanation:

Given are the two angles (3pi)/4, pi/12 and the length 2

The remaining angle:

pi - ((3pi)/4+ pi/12) = (pi)/6

I am assuming that length AB (2) is opposite the smallest angle.

Using the ASA

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

Area=( 2^2*sin((3pi)/4)*sin((pi)/6))/(2*sin(pi/12))

Area=2.7321
