Question

if angle 1 in the picture is 63°, what is the measure of angle 3? why? (1 point) angle 3 is 63° because angle 1 and angle 3 are vertical angles angle 3 is 117° because angle 1 and angle 3 form a line angle 3 is 63° because angle 1 and angle 3 are corresponding angles there is not enough information in the figure to establish this.

Explanation:

Vertical angles are equal. If angle 1 and angle 3 are vertical angles, their measures are the same.

Answer:

Angle 3 is \(63^{\circ}\) because angle 1 and angle 3 are vertical angles.
