The correct Answer is:
To solve the problem, we need to find the angles of a triangle given that one angle measures \(68^\circ\) and the other two angles differ by \(16^\circ\). ### Step-by-Step Solution: 1. **Identify the Angles**: Let the angles of the triangle be \(A\), \(B\), and \(C\). We know that: - \(A = 68^\circ\) - The difference between angles \(B\) and \(C\) is \(16^\circ\). We can express this as: \[ B - C = 16^\circ \] 2. **Express \(C\) in terms of \(B\)**: From the equation \(B - C = 16^\circ\), we can express \(C\) as: \[ C = B - 16^\circ \] 3. **Use the Angle Sum Property**: The sum of the angles in a triangle is always \(180^\circ\). Therefore, we can write: \[ A + B + C = 180^\circ \] Substituting \(A\) and \(C\) into this equation gives: \[ 68^\circ + B + (B - 16^\circ) = 180^\circ \] 4. **Simplify the Equation**: Combine like terms: \[ 68^\circ + B + B - 16^\circ = 180^\circ \] This simplifies to: \[ 2B + 52^\circ = 180^\circ \] 5. **Isolate \(B\)**: Subtract \(52^\circ\) from both sides: \[ 2B = 180^\circ - 52^\circ \] \[ 2B = 128^\circ \] Now, divide by \(2\): \[ B = 64^\circ \] 6. **Find \(C\)**: Now that we have \(B\), we can find \(C\) using the equation \(C = B - 16^\circ\): \[ C = 64^\circ - 16^\circ = 48^\circ \] 7. **Summarize the Angles**: Now we have all the angles of the triangle: - \(A = 68^\circ\) - \(B = 64^\circ\) - \(C = 48^\circ\) ### Final Answer: The angles of the triangle are: - \(A = 68^\circ\) - \(B = 64^\circ\) - \(C = 48^\circ\)
