A triangle has sides A, B, and C. The angle between sides A and B is #(5pi)/12# and the angle between sides B and C is #pi/12#. If side B has a length of 48, what is the area of the triangle?
lets draw a perpendicular line on B .
suppose, the length of the perpendicular is D
now, the problem says, the angle between A and B is
now, by putting the values, B=48 and tan
The area of
now, by putting the value of B and D in the above equation, we get,
