Answer:
80°
Step-by-step explanation:
The reference angle is the smallest angle that the terminal side of a given angle makes with the x-axis.
An angle of -440° lies in the fourth quadrant.
For an angle θ in the fourth quadrant, the reference angle is 360° + θ.
The reference angle is
360° - 440° = 80°
Answer: (2, -3)
Step-by-step explanation:
Look at the point where the two graphed lines cross.
The first number in the solution is the x-value, that is how far to the left or right you count from the center O. 2 to the right +2
The second number in the solution is the y-value, that is how fat up or down you count from the center O. 3 down is -3
When you have those two values, you express them as the "coordinates" of that point. in this case (2, -3)
