That is, $$70^\circ + \left( {23x - 5} \right)^\circ + 110^\circ + \left( {14x} \right)^\circ = 360^\circ$$, Simplifying the left side of this equation, we obtain, $$70^\circ + \left( {23x - 5} \right)^\circ + 110^\circ + \left( {14x} \right)^\circ = 360^\circ$$$$37x + 175^\circ = 360^\circ$$$$37x = 185^\circ$$$$x = 5^\circ$$.
