By alternate segment theorem, angle PQT = 58 degrees. The triangle inscribed in the circle is isosceles, so 2 of the angles in the triangle are the same. Angles ATO and BTO are both right angles as line segment AB is tangent to the circle and OT is a radius of the circle. Try and do this, labelling the size of all the angles you know as you go along and it should be fairly straight forward.
Hope this helps.
