Option A:
230o
Option B:
55o
Option C:
115o
Option D:
.65o
Jamb Maths Solution:
$\begin{align} & \angle OTQ=\tfrac{1}{2}(\angle OPQ) \\ & \text{ }\!\!\{\!\!\text{ }\angle \text{ at circumf}=\tfrac{1}{2}\times \angle \text{ at centre }\!\!\}\!\!\text{ } \\ & \angle OTQ=\tfrac{1}{2}\times {{130}^{\circ }}={{65}^{\circ }} \\\end{align}$
