Question

use the given figure to complete the statement below.
m\angle cob and m\angle are equal.

Explanation:

Step1: Find the measure of \(\angle COB\)

From the figure, \(m\angle COB = 80^{\circ}-60^{\circ}=20^{\circ}\)

Step2: Find the measure of \(\angle DOE\)

From the figure, \(m\angle DOE = 140^{\circ}-120^{\circ}=20^{\circ}\)

Answer:

\(DOE\)
