General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
(x + 1)° + (10x - 7)° + (8x - 4)° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 19x - 10 = 180
- Isolate <em>x</em> term: 19x = 190
- Isolate <em>x</em>: x = 10
