----------------------
Using 12 as zero degrees:
The minute hand is at 90 degs
---------------------------
The hour hand moves 30 degs/hour, so it's at 30*2.25 degs = 67.5
90-67.5 = 22.5 degrees

Draw the picture.
If 12:00 puts both hands at zero degrees,
at 2:15
Note: The hour hand is between 2 and 3; it is 1/4 of the way toward 3.
The hour hand is at (2/12)360 + (1/4)30 = 60+7.5 = 67.5 degrees.
The minute hand is at (3/12)360 = 90 degrees.
---------
The two hands form a 90-67.5= 22.5 degree angle
