Find an angle if its reflex angle is double of the angle.

180d degree

120
 

let the angle be: x
therefore, the reflex angle will be:2x
now, x + 2x = 180^o                                                      (complete angle)
    .^..  3x    =  180^o
    .^.. x      =   180^o/3
   .^..   x       =   60^o

​So, measurement of the real angle = x = 60^o
  ​.^.. measurement of the real angle = 2x = 120<sup>o

Hope you like the answer :)</sup>

 

sorry for the above calculation it would be like this

x + 2x= 360^o
3x = 360^o
x = 360/3^o
x= 120^o

.^.. measurement of the real angle = 120^o
