Question

Two triangles each have adjacent sides of length 120 ft and 180 ft. The first triangle has an angle between the two sides of 40°, while the second triangle has an angle between the two sides of 60°.
What is the approximate difference between the areas of the two triangles?

Answer 1

Area = 1/2 (absinC)
for the triangle with 40°, area = 1/2 (120x180xsin40°) = 6942.106185 sq.ft
for the triangle with 60°, area = 1/2 (120x180xsin60°) = 9353.074361 sq.ft
difference required = 9353.074361 - 6942.106185 = 2410.97 sq.ft
