Answer:

x=16

Explanation:

use the Pythagorean theorem.


\sqrt{a^(2)+b^2 \=
c^(2) Another way, you can do the problem is that you can see


\sqrt{12^2+b^2=
20^(2) 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


√(256\\) = 16
