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°
31 dozen cookies = 372 cookies
372 cookies = 13 cups of flour
1 cookie = 13 ÷ 372 = 0.0349462365591 cups of flour
6 dozen cookies = 72 cookies
72 cookies = 0.0349462365591 x 72 = 2.516 cups
≈ 2.5 cups (nearest 1/4 of a cup)
