Using the Pythagorean theorem you would find X by taking the square root of the base squared (Y^2) subtracted from the hypotenuse squared ( 10^2 = 100)


The equation would be x = √100-y^2


The second answer is the correct one.

Answer:

option 2nd is correct.

Step-by-step explanation:

We have been given a right angled triangle having right angle at B.

So, we can use pythagoras theorem which is:

[tex]hypotenuse^2=side^2+side^2[/tex]   (1)

hypotenuse is the longest side.

which is 10 here,.

And x and y are other two sides

Substituting the values in formula  in (1) we get:

[tex]10^2=x^2+y^2[/tex]

[tex]100=x^2+y^2[/tex]

[tex]\Rightarrow \sqrt{100-y^2}=x[/tex]

Therefore, option 2nd is correct.
