**HINT: The sum of the interior angles in a triangle is 180°
to
65°
65°

Answer 1

x = 50°

General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Geometry

• All angles in a triangle add up to 180°

Explanation:

Step 1: Set up equation

x° + 2(65°) = 180°

Step 2: Solve for x

1. Multiply: x + 130 = 180
2. Isolate x: x = 50°
