• All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up Equation

Every angle must add up to 180°.

(6x - 6)° + 54° + 90° = 180°

Step 2: Solve for x

1. Combine like terms:                    6x + 138 = 180
2. Isolate x term:                              6x = 42
3. Isolate x:                                       x = 7
