As per given by the question,

There are given that a circle for finding the arc AD.

Now,

$\angle APD=(7x+1)^(\circ)$

And,

$\angle CPB=(9x-7)^(\circ)$

Then,

The total sum of the semicircle is 180 degree.

So,

$(7x+1)+(9x-7)=180^(\circ)$

Then,

$\begin{gathered} 7x+1+9x-7=180^(\circ) \\ 16x-6=180^(\circ) \\ 16x=180+6 \\ x=(186)/(16) \end{gathered}$
