Answer:
117
Step-by-step explanation:
Let find some relationships for angle 7. Looking at a angle near 63, Angle 2.
Angle 7 and Angle 2 are same side consecutive interior angles since they are parallel lines. This means they are supplementary. Keep that in mind.
Angle 2 and the 63 degree angles are vertical angles. This means angle 2 measures 63.
Since angle 2 and angle 7 are supplementary and angle 2 equal 63. We can use substitution method to replace angle 2 with 63. equation.
[tex]63 + x = 180[/tex]
[tex]x = 117[/tex]
Angle 7 equal 117
