  1. Explanation:

    We know that,

    The area of a triangle with two sides given and included angle

    A = 1/2 x product of sides x Sin(angle)

    Here the two sides are 8 & 12

    Angle = 150

    Area = 1/2 x 8 x 12 x sin150

    Sin(150) = sin(90+60) = cos(60) = 1/2

    A = 48 x 1/2 = 24

    Area of the given triangle = 24 sq units.
