Answer:
53
Step-by-step explanation:
We can use the Pythagorean Theorem to find x.
Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Where "a" and "b" represent the legs and "c" represents the hypotenuse of the right triangle.
Let's substitute the given lengths into the equation:
[tex]28^2+45^2=x^2\\784+2025=x^2\\x^2=2809[/tex]
Take the square root of both sides:
[tex]\sqrt{x^2}=\sqrt{2809}[/tex]
[tex]x=53[/tex]
