Question

if arc of circle ab = 9 arc cd =4.5 angle aob = 80 then find angle cod and o is the center

Answer 1

Answer:

40°

Step-by-step explanation:

Hello,

Arc of length 9 is having central angle as 80°

Always remember that central angle is directly proportional to length of Arc.

so in second condition circle is same and length of Arc is halved hence central angle will also be halved means our answer is 40°
