Answer:
m= 27
Step-by-step explanation:
m° +66° +m°= 120° (vert. opp. ∠s)
Simplify:
2m° +66°= 120°
2m°= 120° -66°
2m°= 54°
Divide both sides by 2:
m°= 54° ÷2
m°= 27°
m= 27
What are vertically opposite angles?
- When two lines intersect, the angles facing opposite each other are equal
- Abbreviated as 'vert. opp. ∠s'
