What will be the area (in sq. cm) of the triangle ABC if a = 7.8cm, c = 6.8cm and B = 52 degree?
What will be the area (in sq. cm) of the triangle ABC if a = 7.8cm, c = 6.8cm and B = 52 degree? Correct Answer 20.68
Area of triangle = (1 / 2) ac Sin B = (1 / 2) * (7.8) * (6.8) * (Sin52) = (1 / 2) * (7.8) * (6.8) * (0.78) = 20.68 cm2
