Answer:
- The measure of reference angle is
. 
Step-by-step explanation:
Converting
to degrees,

This means
lies in Quadrant 4, and thus its reference angle is 
Since
lies in the fourth quadrant,
and
are negative.
Since
lies in the fourth quadrant,
is positive, and is equal to 
.45 is just 45/100. divide both numbers by 5 to get 9/20.
