If the right triangle shown, ac= bc and ab=4, how long are each of the legs

In a right angle triangle ABC, at C = 90 degree as shown below

AC =BC and AB = 4 units

Let AC=BC= x units

Using Pythagoras theorem:

then substitute the given values we get;

or

Divide both sides by 2 we get;

Simplify:

Therefore, each of the legs would be and  

which expression represents the approximate length of bc?
