If the sum of two angles is 135° and their difference is ; then let us determine the sexagesimal value and circular value of two angles.
converting into sexagesimal value
Let the two angles be x and y.
x + y = 135° …
x - y = 15° …
adding eq.  and eq. 
⇒ 2x = 150°
⇒ x = 75° …
By  and 
y = 60°
converting x to circular
converting y to circular
