- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up Equation</u>
<em>Every angle must add up to 180°.</em>
(6x - 6)° + 54° + 90° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 6x + 138 = 180
- Isolate <em>x</em> term: 6x = 42
- Isolate <em>x</em>: x = 7
