2x + 3 = 2x - 3

It is incorrect :( :(

Step-by-step explanation:

2x + 3 = 2x - 3

or, 2x - 2x = -3-3

or, 0 = -6

If m<COD = 95 degrees, that makes m<AOB a vertical angle to m<COD. That means that you subtract 180 - 95 and you get 85 degrees.

m<AOB = 85 degrees.

My problem with the wording of this problem is that it states that chords AC and BD are perpendicular. That would make both m<COD and m<AOB equal to 90 degrees. But I answered the problem based on your statement that m<COD = 95.
