Mathematics for IGCSE & O level - Pythagoras' Theorem And Trigonometry (Section 1 - No. 31)
What is the correct formula to calculate the area of a triangle given two sides and the included angle?
Area = 1/2 * ab * sinC
Area = 1/2 * (b + c) * h
Area = 1/2 * a * b * c
Area = 1/2 * base * height

This formula applies the sine function with two sides and the included angle to derive the area.
