Solve for x please help with this one too

Answer: 7
Step-by-step explanation:
Here, two chords of the circle is intersecting outside the given circle.
Thus, By the intersecting chord outside the circle theorem,
[tex](x+5)\times 5=10\times 6[/tex]
[tex](x+5)\times 5=60[/tex]
[tex]x+5=12[/tex]
[tex]x =12-5[/tex]
[tex]x =7[/tex]
Hence, the value of x is 7.
