Convert each radian measure to degrees. See Examples 2(a) and 2(b). ―π/6

Guida verificata passo dopo passo

Recall the conversion formula between radians and degrees: \(\text{Degrees} = \text{Radians} \times \frac{180}{\pi}\).

Identify the given radian measure: \(-\frac{\pi}{6}\).

Substitute the radian value into the conversion formula: \(-\frac{\pi}{6} \times \frac{180}{\pi}\).

Simplify the expression by canceling \(\pi\) in numerator and denominator: \(-\frac{1}{6} \times 180\).

Multiply the numbers to find the degree measure (do not calculate the final value here).

Radian Measure

A radian is a unit of angular measure based on the radius of a circle. One radian is the angle created when the arc length equals the radius. Radians provide a natural way to measure angles in terms of the circle's geometry.

Degree Measure

Degrees are a common unit for measuring angles, where a full circle is divided into 360 equal parts. Each degree represents 1/360 of a full rotation, making it intuitive for everyday use and angle measurement.

Conversion between Radians and Degrees

To convert radians to degrees, multiply the radian value by 180/π. This conversion factor arises because π radians equal 180 degrees. For example, converting -π/6 radians involves multiplying by 180/π to get -30 degrees.
