Area of a Triangle. A formula for finding the area of a triangle when given the measures of the angles and one side is area =
where a is the length of the side opposite angle A. If the measures of angles B and C are26° and 61° , respectively, and if a = 19 feet, use the appropriate product-to-sum identity to change the formula so that you can solve for the area of a triangle. Round your answer to two decimal places.
A) 69.30 ft2
B) 3.65 ft2
C) 138.60 ft2
