A triangle has two corners with angles of (3 pi ) / 4 and ( pi )/ 8 . If one side of the triangle has a length of 7 , what is the largest possible area of the triangle?

Largest possible area = 17.3241

Explanation:

Given are the two angles (3pi)/4 and pi/8 and the length 7

The remaining angle:

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

I am assuming that length AB (6) is opposite the smallest angle.

Using the ASA

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

Area=( 7^2*sin(pi/8)*sin((3pi)/4))/(2*sin(pi/8))

Area=17.3241
