Question

please tell me this solution​

Answer 1

Answer:

Let Angle AOC = 70°

Angle BOD = 40°

Angle COD = x°

we know that, one a straight line angle formed is of 180°.

=> angle (AOC + BOD + COD) = 180°

=> (70° + 40° + x° ) = 180°

=> 110° + x° = 180°

=> x° = 180°-110°

=> x° = 70°

hope this helps you.
