\huge\text{$m\angle O=\boxed{11^(\circ)}$}

Since we know that all angles in a triangle add up to
180^(\circ), we can solve for
x and substitute it back into
(x-5)^(\circ) to find
m\angle O.


\begin{aligned}m\angle N+m\angle O+m\angle P&=180\\(5x-8)+(x-5)+(6x+1)&=180\end{aligned}

Remove the parentheses and combine like terms.


\begin{aligned}5x-8+x-5+6x+1&=180\\(5x+x+6x)+(-8-5+1)&=180\\12x-12&=180\end{aligned}

Add
12 to both sides of the equation.


\begin{aligned}12x-12&=180\\12x&=192\end{aligned}

Divide both sides of the equation by
12.


\begin{aligned}x=16\end{aligned}

Now that we have the value of
x, we can substitute it back into
(x-5)^(\circ) to find
m\angle O.


\begin{aligned}m\angle O&=(x-5)\\&=16-5\\&=\boxed{11}\end{aligned}
