Try this option ↓

Step-by-step explanation:

1) according to the condition two angles are equal, then two sides are equal also, it means

2) √x+4=√(5x+4);

3) the 'x' can be calculated if to solve this equation:

$\sqrt{x} +4=\sqrt{5x+4}$ ;

$x+16+8\sqrt{x} =5x+4;$

$4x-12=8\sqrt{x} ;\ => \ x-2\sqrt{x} -3=0;$

$\left \{ {{\sqrt{x} =-1} \atop {\sqrt{x} =3}} \right. \ => \ x=9.$

4) finally, answer: 9.
