thank for

Answer 2

$x = \frac{ - 1 + \sqrt{37} }{2}$

Step-by-step explanation:

$we \: \: know \: \: that \: \: if \: \: DC||AB \: \: then, \\ \boxed{ \frac{AO}{CO} = \frac{BO}{DO} } \\ Now, \: \: \: \frac{3x - 19}{x - 5} = \frac{x - 3}{3} \\ 3(3x - 19) = (x - 3)(x - 5) \\ 9 {x}^{2} - 57 = {x}^{2} - 8x + 15 \\ 8 {x}^{2} + 8x - 72= 0 \\ {x}^{2} + x - 9 = 0 \\ \boxed{x = \frac{ - b + \sqrt{ {b}^{2} - 4ac} }{2a} } \\ x = \frac{ - 1 + \sqrt{37} }{2} \: \: \: \: \:, x ≠ -ve$
