Find the missing value of a triangle one leg is 12 and the long side is 20 what is the other leg?

Burka [1]

Simple,

using the Pythagorean Theorem...

$a^{2} + b^{2} = c^{2}$

You have the hypotenuse (C) and one of the legs (A)

So, plug in what you know...

$12^{2}+ b^{2} = 20^{2}$

144+ $b^{2}$ =400

Now,isolate $b^{2}$

$144+ b^{2} =400$
-144 -144

Leaving you with...

$b^{2} =256$

So, now, $\sqrt{256}$ , to find what b is..

b=16

Thus, your answer.
