Question

O is the centre of the circle.If angle BOD=150 degree,Find m angle BCD and m angle BAD.

Answer 1

Answer:

105 degree

Step-by-step explanation:

angle bad = 1/2 of angle bod on major arc bd

angle on major arc = 360 - 150 = 210

BAD = 210/2 = 105

Answer 2

Answer:

105°

Step-by-step explanation:

angle BOD = 150°

reflex angle BOD = 360-150 = 210° (angle around a point is 360°, the point here is centre O)

angle BAD = reflex angle BOD/ 2 (angle subtended by arc at centre is twice the angle subtended by it at any other point on the circle)

angle BAD = 210/2 = 105°

hope it helped :)
