\(ABC\) is a right triangle with hypotenuse \(35\), and has an angle \(\alpha \) that is equal to \(\sin^{-1}\left(\frac{3}{5}\right) \). \(XYZ\) is a right triangle with hypotenuse \(143\), and has an angle \(\beta\) that is equal to \( \cos^{-1}\left(\frac{5}{13}\right) \). What is the sum of the perimeter of both right triangles?
