In a Right Triangle, the easiest way to solve the measure of the one side when two sides are given is by Pythagorean Theorem.
[tex]\text{ a}^2+b^2=c^2[/tex]Where,
a = Opposite Side
b = Adjacent Side
c = Hypotenuse
Let's rotate the figure to better understand the problem,
Let's now find the value of x,
[tex]\text{ a}^2+b^2=c^2[/tex][tex]\text{ (8)}^2+(6)^2=c^2[/tex][tex]\text{ 64 + 36 = c}^2[/tex][tex]c\text{ = }\sqrt[]{64\text{ + 36}}\text{ = }\sqrt[]{100}[/tex][tex]\text{ c = x = 10}[/tex]Thus, x = 10
