Final answer:
To convert -4.5 radians to degrees, multiply it by the conversion factor 1 radian = 57.3°. The result is -257.85 degrees.
Step-by-step explanation:
To convert radians to degrees, we use the conversion factor 1 radian = 57.3°. In this case, we want to convert -4.5 radians to degrees. Multiply -4.5 by the conversion factor:
-4.5 radians * 57.3°/1 radian = -257.85°
Therefore, -4.5 radians is equal to -257.85 degrees.
