Final answer:
The height of the triangle can be represented by the variable 'C' in the formula Area = 1/2ab sin(C).
Step-by-step explanation:
The formula for the area of a triangle is 1/2 × base × height. In the given formula, the height of the triangle is represented by the variable 'C'. Therefore, 'C' can be substituted for the height of the triangle to derive the formula Area = 1/2ab sin(C).
