General Formulas and Concepts:

Pre-Algebra

  • Order of Operations: BPEMDAS
  • Equality Properties

Geometry

  • A box on an angle signifies a 90° angle
  • All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up equation

x° + 90° + 30° = 180°

Step 2: Solve for x

  1. Combine like terms:                    x + 120 = 180
  2. Subtract 120 on both sides:        x = 60°
I’m assuming the answer is X =60 but I could en wrong.
