A triangle has two corners with angles of pi / 4 and (3 pi )/ 8 . If one side of the triangle has a length of 2 , what is the largest possible area of the triangle?

Largest possible area of the triangle is 2.4142

Explanation:

Given are the two angles (3pi)/8 and pi/4 and the length 1

The remaining angle:

= pi - (((3pi)/8) + pi/4) = (3pi)/8

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)/8)*sin((3pi)/8))/(2*sin(pi/4))

Area=2.4142
