Hey there!:
According to the Pythagorean theorem, the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse (H):
1² + 19² = x²
1 + 361 = x²
x² = 1 + 361
x² = 362
x = √ 362
x = 19.02
Hope this helps!

As per Pythagoras theorem we do know that,
[tex]:\implies\tt{ {1}^{2} + {19}^{2} = {x}^{2} } \\ \\ :\implies\tt{1 + 361 = {x}^{2} } \\ \\ :\implies\tt{ {x}^{2} = 1 + 361} \\ \\ :\implies\tt{ {x}^{2} = 362} \\ \\ :\implies\tt{x = \sqrt{362} } \\ \\ :\implies\tt{x = 19.02}[/tex]
