  • 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

  1. Subtract 5n on both sides:                    n - 4 = 7
  2. Add 4 to both sides:                               n = 11
