Find cos(−2205°) and sin(−2205°). identify the measure of the reference angle.

Reference angle is 45°

Step-by-step explanation:

We have given as

Which can be written as

Here angle is which is equal to 315°

We know that 315° lies in forth quadrant

And in forth quadrant reference angle is given by

So reference angle will be
