Answer:
x = 60°
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- A box on an angle signifies a 90° angle
- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
x° + 90° + 30° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: x + 120 = 180
- Subtract 120 on both sides: x = 60°
quotient is 98 1/2
<u> 0098 </u> 14/28
28 | 2758
<u> 252 </u> * 9 x 28
238
<u> 224 </u> * 8 x 28
14
2758 ÷ 28 = 98 14/28 simplified to 98 1/2
