He was using the measurements of m∠AED & m∠CED, which are supplementary angles, not vertical angles (therefore making them, when combined, equal to 180°).

If they were vertical angles (at the case of m∠AED & m∠BEC, or the other pair), then yes, they will be congruent. But in this case, they are not, so you don't solve it like they are vertical angles.

Answer:

Julio's score change by (-230) or we can say Julio lost 230 points after his first three turns.

Step-by-step explanation:

We are given the following in the question:

Points lost after first turn = 95

Points lost after second turn = 55

Points lost after third turn = 80

We have to evaluate the change in Julio's score after his first three turns.

This could be done by adding three negative integers.

Here we use negative integers to represent Julio's point as these points were lost in the turn.

Change in Julio's score =

$=1^{st}\text{ turn} +2^{nd}\text{ turn} +3^{rd}\text{ turn} \\=(-95) + (-55) + (-80) \\=-230$

Thus, Julio's score change by (-230) or we can say Julio lost 230 points after his first three turns.
