The correct Answer is:
To solve the problem, we need to find the value of \( x \) and each angle of the triangle given the angles as \( 3x^\circ \), \( 2x - 7^\circ \), and \( 4x - 11^\circ \). ### Step-by-Step Solution: 1. **Write the equation for the sum of angles in a triangle**: The sum of the angles in any triangle is always \( 180^\circ \). Therefore, we can write the equation: \[ 3x + (2x - 7) + (4x - 11) = 180 \] 2. **Combine like terms**: Now, we will combine the terms involving \( x \) and the constant terms: \[ 3x + 2x + 4x - 7 - 11 = 180 \] This simplifies to: \[ 9x - 18 = 180 \] 3. **Isolate \( x \)**: Next, we will isolate \( x \) by adding \( 18 \) to both sides of the equation: \[ 9x = 180 + 18 \] Simplifying this gives: \[ 9x = 198 \] 4. **Solve for \( x \)**: Now, divide both sides by \( 9 \): \[ x = \frac{198}{9} \] Calculating this gives: \[ x = 22 \] 5. **Calculate each angle**: Now that we have \( x \), we can find each angle: - For angle \( A \): \[ A = 3x = 3 \times 22 = 66^\circ \] - For angle \( B \): \[ B = 2x - 7 = 2 \times 22 - 7 = 44 - 7 = 37^\circ \] - For angle \( C \): \[ C = 4x - 11 = 4 \times 22 - 11 = 88 - 11 = 77^\circ \] 6. **Final result**: The values of \( x \) and the angles are: - \( x = 22 \) - Angle \( A = 66^\circ \) - Angle \( B = 37^\circ \) - Angle \( C = 77^\circ \) ### Summary: - The measure of \( x \) is \( 22 \). - The angles of the triangle are \( 66^\circ \), \( 37^\circ \), and \( 77^\circ \).
