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
1 x 1 means one 1. So it equals 1.
