Problem
What is the number of degrees in the smaller angle between the hour hand and the minute hand on a clock that reads seven o'clock?
Solution
The smaller angle makes up 
of the circle which is the clock. A circle is 
, so the measure of the smaller angle is
![\[\frac{5}{12}\cdot 360^\circ = 150^\circ \rightarrow \boxed{\text{D}}\]](http://latex.artofproblemsolving.com/d/d/7/dd767c8b12bbb3f732ee0c22b3af7c2a3d977c2c.png)
