Question

if the measure of angle 3 is 55 degrees, what is the measure of angle 4?

Explanation:

Step1: Identify the relationship between angle 3 and angle 4

Angle 3 and angle 4 are vertical angles.

Step2: Use the vertical - angles theorem

Vertical angles are congruent. So, \(m\angle4=m\angle3\).

Answer:

\(55\) degrees
