The missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.
<h3>How to find vertically opposite angles?</h3>
We want to prove that m∠BOC = 90°.
We are given that m∠AOB is a right angle triangle. Thus;
m∠BOC must also be equal to 90°
Now, since m∠BOC and m∠AOB are right angles, then it means that we must equally say that m∠DOA and m∠BOC are vertical opposite angles and they are as such equal.
Thus, the missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.

Answer:
The answer is 4
Step-by-step explanation:
2x + 5 = 13
Now, Subtract 5 from both side we get,
2x + 5 - 5 = 13 - 5
2x = 8
Then, Divide both side by 2 we get,
2x/2 = 8/2
x = 4
Thus, The answer is 4
