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 12, what is the area of the triangle?
Area = 18 units
The given triangle is sketched as in the figure above. Angle B would be
Side b is 12. It is the hypotenuse because it is opposite the right angle B.
For area, base and altitude is required. In this case it is side 'a' and side 'c'.
Side 'c' =
Side 'a' =
Area = 18 units.
