A triangle has two corners with angles of # pi / 4 # and # (3 pi )/ 8 #. If one side of the triangle has a length of #3 #, what is the largest possible area of the triangle?
1 Answer
Explanation:
Two of the angles given are
Now, for the area to be as large as possible, its sides must be as large as possible. For this to happen, the one side that is specified must be the smallest one - and hence must be opposite the smallest angle - in this case
The height of this triangle
Thus the area is
