Question
If angle between two sides of 3 cm & 2 cm of a triangle
is 30°. what is the area of the triangle ?Solution
Area of the triangle = 1/2 X a X b X Sin θ where ɵ is the angle between two sided a & b of the triangle; So Area of the triangle = 1/2 X a X b X Sin θ = 1/2 X a X b X sin 300 = 1/2 X 3 X 2 X 1/2 = 3/2 cm2
