General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Equality Properties
- Vertical Angles: Angles that are across from each other and are congruent
Step-by-step explanation:
Step 1: Set up equation
Vertical angles must be congruent.
(6n - 4)° = (5n + 7)°
Step 2: Solve for n
- Subtract 5n on both sides: n - 4 = 7
- Add 4 to both sides: n = 11
