Help please!

Is there a way to complete the angles of this circle or do we have insufficient information. The line does not pass through the centre of the circle so none of the rules that I've learnt are working.

Thanks for your help

In part (b) those angles in the centre are not 90 degrees

How about rules for triangles?

There is insufficient information to find angle $\displaystyle f^{\circ}$ in part b.
