The correct Answer is:
To find the two supplementary angles that are in the ratio of 3:2, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the concept of supplementary angles**: Supplementary angles are two angles whose sum is 180 degrees. 2. **Set up the ratio**: Let the two angles be represented as \(3x\) and \(2x\), where \(x\) is a common factor. 3. **Write the equation for supplementary angles**: Since the angles are supplementary, we can write the equation: \[ 3x + 2x = 180 \] 4. **Combine like terms**: Combine the terms on the left side of the equation: \[ 5x = 180 \] 5. **Solve for \(x\)**: Divide both sides by 5 to find the value of \(x\): \[ x = \frac{180}{5} = 36 \] 6. **Find the angles**: Now substitute \(x\) back into the expressions for the angles: - First angle: \[ 3x = 3 \times 36 = 108 \text{ degrees} \] - Second angle: \[ 2x = 2 \times 36 = 72 \text{ degrees} \] 7. **State the final answer**: The two supplementary angles are: - \(108\) degrees - \(72\) degrees
