The correct Answer is:
To solve the problem, we need to find the angle between the bisectors of the other two angles in a triangle where one angle is given as \(130^\circ\). ### Step-by-Step Solution: 1. **Identify the Angles of the Triangle**: - Let the angles of the triangle be \(A\), \(B\), and \(C\). - Given that \(A = 130^\circ\). 2. **Use the Triangle Sum Property**: - The sum of the angles in a triangle is \(180^\circ\). - Therefore, we can write the equation: \[ A + B + C = 180^\circ \] - Substituting the value of \(A\): \[ 130^\circ + B + C = 180^\circ \] 3. **Calculate the Sum of the Other Two Angles**: - Rearranging the equation gives: \[ B + C = 180^\circ - 130^\circ = 50^\circ \] 4. **Find the Angle Between the Angle Bisectors**: - The angle between the bisectors of angles \(B\) and \(C\) can be calculated using the formula: \[ \text{Angle between bisectors} = \frac{1}{2} \times (B + C) \] - Substituting the value of \(B + C\): \[ \text{Angle between bisectors} = \frac{1}{2} \times 50^\circ = 25^\circ \] 5. **Conclusion**: - Therefore, the angle between the bisectors of the other two angles \(B\) and \(C\) is \(25^\circ\). ### Final Answer: The angle between the bisectors of the other two angles can be \(25^\circ\).
