Question 4 on page 12.

Could someone give me some hints on how to do this? I have no idea how. All I know is that we could draw a line from the center of the circle to Q, which I think would be perpendicular to that tangent. Also if we draw a horizontal line from the center of the circle to the tangent, the angle between them will be theta.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
