Question

In a circle a the measure of arc 80degree. the measure of angle bad is

Answer 1

Given:

a circle is given

It is given that the arc BD=80 degree.

Find:

we have to find angle BAD and angle BCD.

Step-by-step 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.
