x=16

Step-by-step explanation:

use the Pythagorean theorem.

[tex]\sqrt{a^{2}+b^2 \[/tex]= [tex]c^{2}[/tex]          Another way, you can do the problem is that you can see

[tex]\sqrt{12^2+b^2[/tex]= [tex]20^{2}[/tex]     that 12 divided by 4 is 3 and 20 divided by 4 is 5, which is

144+b^2=400     the two numbers from the special 3,4,5 triangle, and since

-144        -144      you have figured that much out, you can multiply 4*4 and

------------------------ get 16.

      b^2=256

[tex]\sqrt{256\\}[/tex] = 16
