The angle formed by the hands of a clock at 
is:
Solution
To find the angle of the clock, we first have to determine where the hands are. The time is 
hours, so the hour hand would be 
degrees clockwise. As the clock is a quarter of the way through the hour, the minute hand is 
degrees clockwise.
Thus, we can say that the angle formed by the hands is $90 - 67.5 = 22\frac{1}{2} degrees. \boxed{\textbf{(E) }$ (Error compiling LaTeX. Unknown error_msg).
