in triangle DEF,<D=50 degree, DE=14 meters, and DF=10 meters. find the area of triangle DEFto the nearest tenth of a square meters

  • Math -

    If you have a triangle with sides a and b and Ø is the angle between them, then the area is
    (1/2)ab sinØ

    you have that condition, so
    Area = (1/2)(14)(10)sin50° = appr 53.623
    or to the nearest tenth ----> 53.6 m^2
