Q:

What is the area of an obtuse angled triangle given below with two sides are 8 and 12 and the angle included between two sides is 150 deg?

 A) 48 sq units B) 24 sq units C) 12 sq units D) 6 sq units

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.
