Question

If OD is perpendicular to AB, and ∠DOC = 50°, find m∠BOC - m∠AOC.
​

Answer 1

Answer:

given :-

angle DOC = 50° and angle BOD = 90°

i.e angle BOC = 90°+50° = 140°

angle BOC + angle AOC = 180° (angle sum property)

140° + x = 180°

x = 180° - 140°

x = 40°

i.e angle AOC = 40°

now,

angle BOC - angle AOC

140° - 40° = 100°

Answer 2
