Question

explore the properties of angles formed by two intersecting chords. 1.the intersecting chords form vertical angles. if (mangle deb = 105^{circ}), then (mangle aec=square^{circ}). (mangle deb = 105^{circ})

Explanation:

Step1: Recall vertical - angle property

Vertical angles are congruent.

Step2: Identify vertical angles

\(\angle DEB\) and \(\angle AEC\) are vertical angles.

Answer:

105
