Work Step by Step

Step 1: To convert from radians to degrees, we need to multiply the angle in radians by $(\frac{180^{\circ}}{\pi})$, $-3.47189$ radians$=-3.47189(\frac{180^{\circ}}{\pi})$ Step 2: Using a calculator, $-3.47189(\frac{180^{\circ}}{\pi})\approx-198.9246^{\circ}$ Step 3: Converting decimal degrees to minutes, $0.9246(60')\approx55'$ Step 4: Therefore, $-198.9246^{\circ}=-198^{\circ}55'$
