Convert each measure to degrees. Round answers to the nearest hundredth if needed. a.) π/9 b.) - 2π/3

To convert an angle from units of radians to the units of degrees, we need a conversion factor to multiply. From what I've learned, we just have to multiply the value 180° / π. We convert as follows:

a.) π/9 (180°/π) = 20°

b.) - 2π/3 (180°/π) = - 120°
