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 = 105°.

1. find the sum of the angle measures: m∠deb + m∠aec =

m∠deb = 105°
m∠aec = 105°

Explanation:

Step1: Identify given angle measures

Given \(m\angle DEB = 105^{\circ}\) and \(m\angle AEC=105^{\circ}\)

Step2: Calculate the sum

\(m\angle DEB + m\angle AEC=105^{\circ}+ 105^{\circ}=210^{\circ}\)

Answer:

\(210\)
