Question

what squared add what squared equals what squared

Answer 1

If $x$ is 'what squared' and $x^2+x^2=x^2$ , then $x=0.$

Assume that the value of 'what squared' may differ.

Let the measures of Right angled triangle be as follows:

Opposite side = 4 cm;

Adjacent side = 3 cm;

Hypotenuse = 5 cm;

$$4^2 + 3^2 = 5^2$$

$$Opposite \space side^2 + Adjacent \space side^2 = Hypotenuse^2$$

4 square add 3 squared equals 5 squared
