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°
700 to the nearest hundred
1. 7 = 4s + 19
7 - 19 = 4s
-12 = 4s
s = -3
2. x/4 + 8 = 16
x + (8 × 4) = 16 × 4
x + 32 = 64
x = 32
Answer:
It can't be factored
