Work Step by Step

Step 1: To convert from radians to degrees, we need to multiply the angle in radians by $(\frac{180^{\circ}}{\pi})$, $1.74$ radians$=1.74(\frac{180^{\circ}}{\pi})$ Step 2: Using a calculator, $1.74(\frac{180^{\circ}}{\pi})\approx99.69466^{\circ}$ Step 3: Converting decimal degrees to minutes, $0.69466(60')\approx42'$ Step 4: Therefore, $99.69466^{\circ}=99^{\circ}42'$
