Omar wants to determine cos(-3) using the ratios of the 30° he use this information to determine cos(-3)?
60° - 90° right triangle. How should
Use the reference angle of 30° and the fact that is in the fourth quadrant to determine cos
Use the reference angle of 60° and the fact that - 25 is in the fourth quadrant to determine cos
Use the reference angle of 30° and the fans that – is in the third quadrant to determine cos(-3) = ***
Use the reference angle of 60° and the fact that - 25 is in the third quadrant to determine cos
s(-3) = -1
