The area K of a triangle whose base is b and whose height is

The area K of a triangle, whose base is b and whose height is h is. If two sides a and b the included angle C are known in a triangle, then the area K is found using the formula K =. The area K of a triangle with sides a, b, and c is K = where s =. In problems 5-12, find the area of each triangle. Round answers to two decimal places.

Solution

Area = 0.5 x base x height

=0.5 x 4 x 3sin30 = 3
