Question 717562
Co-terminal angles will have the same tan's (and sin's, cos's, etc.) as each other. So we want to find a co-terminal angle that we recognize (between 0 and 360). Co-terminal angles are 360 degrees apart from each other. So start adding 360's to -675 until you get an angle between 0 and 360. Then find the tan of that angle. That tan will be the same as the tan(-675).
