Answer:

x=6.25

Step-by-step explanation:

What you do is add up all the angles equal to 180 because a triangle always adds up to 180 degrees and you are given all angles.

Space

Answer:

x = 25/4

General Formulas and Concepts:

Pre-Algebra

  • Order of Operations: BPEMDAS
  • Equality Properties

Geometry

  • All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up equation

(22x + 1)° + (6x - 17)° + (4x - 4)° = 180°

Step 2: Solve for x

  1. Combine like terms:                         32x - 20 = 180
  2. Isolate x term:                                   32x = 200
  3. Isolate x:                                            x = 25/4
