"Find the area of a triangle with side lengths 18 and 20 and included angle 6 degree."
---------
Area = bh/2
h = 18*sin(6) (or 20*sin(6))

"Find the area of a triangle with side lengths 18 and 20 and included angle 6 degree."

I take it that this is not a right-triangle.

Therefore, area = %281%2F2%29%2818%29%2820%29%28sin_6%29 ----- 180 * sin(6) ≈ highlight_green%2818.82%29 sq units.
