Question

What is the size of angle a?

Answer 1

60 degrees

Explanation:

The total angles of a circle add up to 360 so to find a missing angle, subtract the figures already given from 60. The angles given total to (140+125+35) = 300. To find angle a, you subtract the 300 from 360. 360-300 = 60 degrees. Therefore, angle a is 60 degrees

Answer 2

Answer is going to be 60, I’m not really sure but here you go
