Question

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

Answer 1

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°
