X=5

Answer:

x = 5

Step-by-step explanation:

Pythagorean theorem states [tex]a^{2}+b^{2}=c^{2}[/tex] (that is, the sum of the squares of the length of each side of a right triangle equals the length of the hypotenuse squared.

[tex]4^{2}+3^{2}=x^{2}[/tex]

This simplifies to [tex]25=x^{2}[/tex]

Take the square root of both sides to get the value of x.

[tex]\sqrt{25}=\sqrt{x^{2}}[/tex]

And finally, this simplifies to x=5.
