Hi


 


let the angles be


 


x-d, x, x+d


x+d=5x-5d             -------1


Also, 4x=6d


=> d=2x/3


 


Also (x-d) +(x)+(x+d)   ==  180 degrees


or 3x = 180


or x=60 degrees


=> d=40 degrees


 


=> the angles are x-d, x, x+d


 


or 20, 60, 100 degrees


 


For the measure in radians, multiply each angle by pi/180.


 


Thanks,


Rajat
