1. The problem is to convert an angle from radians to degrees. 2. The formula to convert radians to degrees is: $$\text{degrees} = \text{radians} \times \frac{180}{\pi}$$ 3. Given the angle is $-3.5$ radians, substitute into the formula: $$-3.5 \times \frac{180}{\pi}$$ 4. Calculate the multiplication: $$-3.5 \times \frac{180}{\pi} = -3.5 \times 57.2958...$$ 5. Multiply: $$-3.5 \times 57.2958 = -200.5353$$ 6. Round to the nearest tenth: $$-200.5$$ Therefore, $-3.5$ radians is approximately $-200.5$ degrees.
