Answer:
x=20
Step-by-step explanation:
The Pythagorean theorem is
, where a and b are the legs (the smaller sides) and c is the hypotenuse. So, plugin 12 and 16 for a and b, then solve. This looks like
. Next, simplify the equation,
=144 and
=256; then add 144+256. The new equation is 400=
. The final step is to take the square root of both sides. Since
=20, x (the hypotenuse) must equal 20.
