sum of \( \left(3 x^{3}-8 x^{2}+5 x+15\right) \) and \( \left(4 x^{2}+7 x-11\right) \)

From a point \( T \), a tangent \( T P \) at point \( P \), is drawn to a circle with centre \( O \). A secant TQR (point \( Q \) is near to point \( T \) ) is drawn from the point \( T \). \( \triangle P Q R \) is inscribed into the circle by joining the points \( P, Q \) and \( R \). Draw lines \( O Q \) and \( O R \). If \( \angle P T Q \) is \( 27^{\circ} \) and \( \angle T P Q= \) \( 55^{\circ} \), what is the degree measure of \( \angle R O Q \) ? 1.86 2.94
