Question

in the given figure angle AOC and angle BOC form a linear pair angle BOC is equal to 75 degree find the value of angle AOC

Answer 1

If angle AOC and BOC are linear pair then angle AOC+BOC=180°
so 75+BOC=180°
BOC=180-75
BOC=105°

Answer 2

AngleAOC+angleBOC=180°(angle on a straight line is of 180) BOC is 75 so AOC=180-75 =105
