Convert from Degrees to Radians -420

Problem

−420

Solution

1. Identify the conversion factor between degrees and radians, which is (π* rad)/180

2. Multiply the given angle in degrees by this conversion factor.

−420⋅π/180

3. Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 60

(−420)/180=(−7)/3

4. Combine the simplified fraction with π to get the final radian measure.

−(7*π)/3

Final Answer

−420=−(7*π)/3
