Give signs of angle

The question on my book says this, "Give the signs of the sine, cosine, and tangent functions for each angle.".
The angle is 129degrees, that is all they give me. I dont know where to start to solve this. Can someone give me a starting point?
Are they asking for a sign as in + or -? Any help would be appreciated.
Thanks,

Re: Give signs of angle

when the angle is 129degrees,it is in the second quadrant, only sine is positive("+"), the others are negative ( "-")
