You can put this solution on YOUR website!Find the area of a triangle if side b = 5, side c = 4, and angle A = 20 degrees.
--------------------
There is a formula that says Area of a triangle = absinC
----------------
Your Problem:
Area = bcsinA
Area = 5*4*sin(20)
Area = 20sin(20)
Area = 6.84...
Cheers,
