The lenght of each of the two sides of an isisceles triangle is 10 meters. The angle between the two congruent sides is x. find the area of the triangle as a function of x/2.

  • math - ,

    area = 1/2 base * height
    = 1/2 * 2(10sin(x/2)) * 10cos(x/2)
    = 100 sin(x/2)cos(x/2)
    = 50 sin(x)
