| 1. Let us denote the degree measure of the smaller angle of the rhombus through xy
2. Define the degree measure of the larger angle of the rhombus:
2 * x = 2x.
3. Let’s compose and solve the equation:
2x + x = 180˚;
3x = 180˚;
x = 180˚: 3;
x = 60˚.
4. The degree measure of the smaller angle of the rhombus is x = 60˚.
5. What is the degree measure of the larger angle of the rhombus?
180˚ – 60˚ = 120˚.
6. What is the area of the rhombus?
6 ^ 2 * sin60˚ = 36 * √3 / 2 = 18√3 (cm ^ 2)
Answer: the area of a rhombus is 18√3 cm ^ 2.
