\[ \sin (225)=\sin (360255)=\sin (105)=\sin (45+60)=\\\sin (45)) \cos (60)\sin (60) \cos (45) \]

If you add 360 to an angle you do not change the sine of that angle sin(360+y) = sin(y) sin( 360 +(x)) =sin(x) = sin(x) If you do not know these elementary facts, please review them in your book or notes.
