How to find the area of an oblique triangle

The video tutorial explains how to calculate the area of oblique triangles using the sine rule. It begins by introducing the formula for the area of a triangle and then applies it to oblique triangles by incorporating the sine of an angle. The instructor demonstrates how to substitute given values into the formula, including converting angle measurements from degrees and minutes to decimal form. The lesson concludes with a final calculation of the area, emphasizing the importance of understanding the relationship between the base, height, and sine of the angle.

Explain how to convert 30 minutes into a decimal for the sine calculation.
