Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

BO=OC (radius)

Therefore, angle OBC = angle OCB = n.

Now, angle BOC = angle BAC/ 2= n/2

In triangle OBC,

Angle OCB + Angle OBC + angle BOC = 180 (A. S. P. T.)

m + m + n/2 = 180

4m+n = 180 × 2

4m+n = 360
