if we us the method asquared + b squared =c squared x=8 cuz 
8*8=64
6*6=36
36+64=100 
and 10*10 =100
so x=8

hope this helps

Hello!

You can use the Pythagorean Theorem

[tex] a^{2} + b^{2} = c^{2} [/tex]

c is the hypotenuse which is the side across the right angle
a and b are the other sides

Put in the values you know

[tex] a^{2} + 6^{2} = 10^{2} [/tex]

Square the numbers

[tex]a^{2} + 36 = 100[/tex]

Subtract 36 from both sides

[tex] a^{2} = 64 [/tex]

Take the square root of both sides

a = 8

The answer is 8

Hope this helps!
