Convert the given angle from radians to degrees

The video tutorial explains the concept of converting angles between radians and degrees. It begins by discussing equivalent ratios using time as an example, then compares radians and degrees as different units of measuring angles. The tutorial provides a step-by-step guide on converting radians to degrees by multiplying by 180/π and vice versa by multiplying degrees by π/180. The instructor uses examples to clarify the conversion process and addresses questions to ensure understanding.
