Given:
a circle is given
It is given that the arc BD=80 degree.
Find:
we have to find angle BAD and angle BCD.
Explanation:
as we know arc BD = angle BAD
Therefore, angle BAD = 80 degree
Now angle BCD = (1/2) *Angle BAD
Hence, Angle BCD = (1/2)*(80) = 40 degree
Conclusion:
Therefore, angle BAD = 80 deg and
angle BCD = 40 deg.
