Answer:
cos 225° = 
sin 225° = 
tan 225° = 1
Step-by-step explanation:
I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45° (225 - 180 = 45)
cos and sin are negative in the 3rd quadrant and the tan is positive
cos 225° = - cos 45° = 
sin 225° = -sin 45° = 
tan 225° = tan 45° = 1
