The correct Answer is:
To solve the problem, we need to find the measure of angle P where the angle bisectors of angles CBD and BCE meet. Given that angle A = 82 degrees, we can use the theorem related to the angle bisectors in this configuration. ### Step-by-Step Solution: 1. **Understand the Configuration**: - We have triangle ABC with angle A = 82 degrees. - The sides AB and AC are extended to points D and E respectively. - We need to find angle P, which is formed by the intersection of the angle bisectors of angles CBD and BCE. 2. **Identify Angles**: - Let angle ABC = B and angle ACB = C. - By the triangle angle sum property, we know: \[ A + B + C = 180^\circ \] - Substituting the known value: \[ 82 + B + C = 180 \] \[ B + C = 98^\circ \] 3. **Using the Angle Bisector Theorem**: - The theorem states that if we have two angle bisectors meeting at a point, the angle formed at that point (angle P) can be calculated using the formula: \[ \angle P = 90^\circ - \frac{1}{2} \angle A \] 4. **Substituting the Value of Angle A**: - Now substituting the value of angle A into the formula: \[ \angle P = 90^\circ - \frac{1}{2} \times 82^\circ \] \[ \angle P = 90^\circ - 41^\circ \] \[ \angle P = 49^\circ \] 5. **Final Answer**: - Therefore, the measure of angle P is: \[ \angle P = 49^\circ \]
