To convert a degree measurement to a radian measurement, multiply the angle by the conversion ratio. One degree is equal to 0.017453 radians, so use this simple formula to convert: The angle in radians is equal to the degrees multiplied by 0.017453.

Answer 2

Answer: -0.3927 radian

Step-by-step explanation:

-22°30' = -22° +( $\frac{30}{60}$)°

            = -22.5°

We know, 1° = $\frac{\pi }{180}$ radian

              ∴ -22.5° = $\frac{\pi .(-22.5)}{180}$ radian

                            = -0.3926 radian
