Find the radian measures corresponding to the following degree measures:
(i)
25°
Answer
5π/36 radians
(ii)
-47° 30'
Answer
-19π/72 radians
(iii)
240°
Answer
4π/3 radians
(iv)
520°
Answer
26π/9 radians
Explanation
To convert degree measures to radian measures, we use the relation provided in the text: 180 degrees = π radians. This implies that 1 degree = π/180 radians. For part (ii), the minutes (30') are converted to degrees (0.5 degrees) before applying the conversion formula.
