  • All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up equation

n° + n° + 50° = 180°

Step 2: Solve for n

  1. Combine like terms:                    2n + 50 = 180
  2. Isolate n term:                              2n = 130
  3. Isolate n:                                       n = 65
