Question

What is the value of x?

Enter your answer in the box.
x=

Answer 1

X=10 - 6

= 4

X= 4

answer is : 4

Answer 2

By the Pythagorean Theorem, the length of x is

a^2 + b^2 = c^2                    Pythagorean Theorem
6^2 + b^2 = 10^2                 Substitute known variables
6^2 + b^2 - 10^2 = 0            Subtract 10^2 from each side 
6^2 - 10^2 = b^2                  Subtract b^2 from each side
√6^2-10^2 = √b^2                Take square root of each side
8 = b                                     Simplify

So, the length of x is 8. I hope this helps!
