# 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

15°

Let the two angles be x and y.

x + y = 135° …[1]

x - y = 15° …[2]

adding eq. [1] and eq. [2]

2x = 150°

x = 75° …[3]

By [1] and [3]

y = 60°

converting x to circular

converting y to circular
