At 3 hours 45 minutes there is not an acute angle between the hands of the clock (unless you extend the hands backwards).

Angle between the hands of a clock=|11M-60H|/2i.e. M-Minutes=35(here)H- Hours=7(here)∴ The angle b/w hands of a clock=|11*35-60*7|/2=17.5°

It is a obtuse angle.
get yourself a cartesian circle, or just look at one online and translate it from there 3,6,9, and 12 would all be 90 deg increments.
