Answer:
A. x = [tex]\sqrt{104}[/tex]
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean Theorem, where a and b are legs and c is the hypotenuse (the longest side of the triangle, across from the right angle).
a^2 + b^2 = c^2
Plug in the values.
2^2 + 10^2 = c^2
4 + 100 = c^2
104 = c^2
[tex]\sqrt{104} = \sqrt{c^{2}}[/tex]
c = [tex]\sqrt{104}[/tex]
The answer is A. x = [tex]\sqrt{104}[/tex]
