A triangle has two corners with angles of ( pi ) / 3 π3 and ( pi )/ 6 π6. If one side of the triangle has a length of 8 8, what is the largest possible area of the triangle?

Area of the triangle Delta ABC = (1/2) * 8 * 13.8564 = color(blue)(55.4256) sq. units

Explanation:

Three angles of the triangle are alpha = pi/3, beta = pi/6, gamma = pi - (pi/3 + pi/6) = pi/2

It’s a right triangle with sides in the ratio 1 : sqrt3 :2, length ‘2’ being the hypotenuse.

To get the maximum area, length ‘8’ should correspond to the smallest angle pi/6.

Hence the sides are 8, 8sqrt3, 8*2

I.e. 8, 13.8564, 16

Area of the triangle Delta ABC = (1/2) * 8 * 13.8564 = color(blue)(55.4256) sq. units
