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:
76.75
Step-by-step explanation:
83.5 + 70= 153.5
153.5 / 2 = 76.75
Your grade would be 76.75.

-7 = 1 + 2/3n
Subtract 1 from both sides:
-8 = 2/3n
Multiply both sides by 3:
-24 = 2n
Divide both sides by 2:
N= -12
The mean is the average. If the mean of 4 letter (a,b,cd) is 12, the sum of them would be 12x4 =48
Now add e to the total: 48 + 50 = 98
The mean is the total divided by the quantity:
Mean = 98 /5 = 19.6
