Answer:
x = 2√13
Step-by-step explanation:
First, we can put out a lot of equations to see if we can make a system:
<em>x² = y² + 4²</em>, x² + z² = 13², xz = 13y, <em>y² + 9² = z²</em>
Substitute 4 into 1: <em>x² = (z² - 9²) + 4²</em>
System 2 and substitution: <em>x² + z² = 169, x² - z² = -65</em>
Elimination: 2x² = 104
Divide: x² = 52
Square root: x = √52 = 2√13
Answer:
Answer: The set {1, 2, 3} has 8 subsets.
A set with 'n' elements in it can have 2n subsets.
We know, Area of a Hexagon = 3√3a² / 2
A = 3√3 /2 * 10²
A = 3√3 * 100/2
A ≈ 259.81 m²
In short, Your Answer would be: 259.81 m²
Hope this helps!
