Question

explore the properties of angles formed by two intersecting chords. 1. the intersecting chords form vertical angles. if m∠deb = 105°, then m∠aec = \boxed{}°. m∠deb = 105°

Explanation:

Step1: Identify vertical angles

∠DEB and ∠AEC are vertical angles.

Step2: Apply vertical angle property

Vertical angles are equal, so m∠AEC = m∠DEB.

Answer:

105
