You can also draw a line from O to A which splits the quadrilateral figure into two equal right angled triangles (of which half of one angle at A is 25•)
- then you go 90• minus 25• is 65•
- since half of the angle X (at O) is 65•, the full angle will be 65• times 2 which gives us 130•

* YOUR ANS IS CORRECT

You can make it two tringles then divide 50 on 2 equal 25, then 180-90-25 equal 65, after that 65 multiple by 2 = 130

I like your precise procedures of doing this. However, in a situation that you need to be hurry, I suggest that you should select the nearest number to 180 since it seems to be very near to 180
