Understand the conversion factor between radians and degrees: 1 radian is equal to 180/π degrees.

To convert an angle from radians to degrees, multiply the radian measure by the conversion factor (180/π).

Apply the conversion to the given angle: Multiply −5π/6 by 180/π.

Simplify the expression: Cancel out π in the numerator and denominator, then multiply −5/6 by 180.

Calculate the result of the multiplication to find the angle in degrees.
