Angle 3 is 117°
117
°
because angle 1 and angle 3 form a line.
Angle 3 is 117 degrees because angle 1 and angle 3 form a line.
Angle 3 is 63°
63
°
because angle 1 and angle 3 are vertical angles.
Angle 3 is 63 degrees because angle 1 and angle 3 are vertical angles.
Angle 3 is 63°
63
°
because angle 1 and angle 3 are corresponding angles.

To determine the measure of angle 3 based on the information given about angle 1, we can use the properties of angles formed by intersecting lines.
Since angle 1 is 63°, we need to analyze the relationships between the angles:
Therefore, angle 3 must also be 63°.
The correct response is: Angle 3 is 63° because angle 1 and angle 3 are vertical angles.
