Find the area of a rhombus, one of the corners of which is 120 degrees, and the side is 10 cm.

The area of a rhombus is equal to the product of the lengths of its sides by the sine of the angle between them.

S = AВ * AD * Sin120 = 10 * 10 * √3 / 2 = 50 * √3 cm2.

Answer: The area of the rhombus is 50 * √3 cm2.
