    The area of △ABC with side lengths b = 9 and  c = 14,

    and included angle A = 145°

    a: 21.99  b: 9.00  c: 14.00  A: 145.00°  B: 13.58°  C: 21.42°  Height: 3.29  Sqr: 36.14

    Area of the triangle = 36.17355 units^2

    Area of triangle: 0.5*9*14*sin(145) = 36.1 square units rounded to the nearest tenth
