How to find the area of a triangle using sine?

To find the area of a triangle using the sine function, you can use the formula:

Area = 1/2 ab sin C

The formula is used to calculate the area of a triangle when you know the lengths of two sides (a and b) and the measure of the included angle (C). It’s important to note that C should be the angle between sides a and b.

Find the area of a triangle with sides a=6 units, b=8 units, and the included angle C=30. We want to find the area of this triangle.

Apply the Formula: Area = 1/2 ab sin(C)

Area = 1/2 × 6 × 8 × sin (30) = 12 square units
