Common response, but it's incorrect. What about the hour hand? It's not pointing directly at the 9 anymore...

60 degrees, or 300 degrees whichever way you want to look at it.

105 degrees: if the hour hand is right at 9, and the minute had was right at 30 then it would be 90 degrees. but since we're 30 minutes into the hr, the hour hand will be (theoretically) half waybetween 9 and 10pm. so you need to calculate that additional variation.

If have the arms 3 hrs apart makes a perfect 90 degrees, then each hr would equal 30 degrees -> thus a half hr would result in a 15 degrees. 90+15= 105 degrees
