We will use the formula:
Area = 1/2*a*c*sinB

where a and c are the length of the sides and B is the angle between those 2 sides

Area = 1/2*5*8*sin42
Area = 20*sin42
sin 42 = 0.669130606359
Area = 13.38261212718

Rounded to the nearest tenth Area is equal to 13.4

Find the area of the triangle with A =42 degrees, b = 8 feet, and c = 5 feet. Round to the nearest tenth.
