Answer:
[tex]\sqrt{253}[/tex]
Step-by-step explanation:
The question asks to use the Pythagorean Theorem...
which is [tex]a^{2} + b^2 = c^2[/tex]
1. Note that c is always the hypotnuse (the longest side of the triangle)
2. Note that a and b represent both legs of the triangle
3. Find b using pythagorean theorem (x = b)
[tex]6^2 + b^2 = 17^2\\36 + b^2 = 289\\b^2 = 253\\b=\sqrt{253} \\[/tex]
Since b is the missing side x, then [tex]x = \sqrt{253}[/tex]
