For the triangle ABC AB = 6, B=pi/4, C=pi/6.
As the angles of a triangle have a sum of pi. A = 7*pi/12
Use the property sin A/a = sin B/b = sin C/c
c = 6, C = pi/6, B = pi/4 and A = 7*pi/12
=> sin (pi/6)/6 = sin (pi/4)/b = sin (7*pi/12)/a
=> b = 8.485
=> a = 11.59
The perimeter of the triangle is 6 + 8.48 + 11.59 = 26.07
