Q6 of 25 Page 276

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
