The missing reason in step 3: is vertical angles are congruent, while the missing reason in step 5 is: definition of congruency.
<h3>What are Vertical Angles?</h3>
Two angles are referred to as vertical angles is:
- They share the same vertex angle.
- They are non-adjacent angles.
- They do not share a common side.
<h3>What is the Vertical Angles Theorem?</h3>
According to the vertical angles theorem, two angles that are vertical angles must be congruent to each other, that is, they are equal in measure.
In the image given, as attached below, angle EDF and angle ADC are vertical angles pair. Therefore, based on the vertical angles theorem, they have equal measure (they are congruent to each other).
Thus, the missing reason in step 3: is vertical angles are congruent, while the missing reason in step 5 is: definition of congruency.

Answer:
The true statements are:
The cost of 9 magnets is $3.
The cost of 6 magnets is $2.
The cost of 3 magnets is $1.
Step-by-step explanation:
equivalents ratios are two or more ratios that express the same relationship between the numbers involved. In order to calculate the equivalent ratios that are equal, when the numbers involved are divided, they ought to give the same result. In the answer chosen above the ratios in each case are equivalent because:
if the cost of 9 magnets is $3;
9 magnets = $3
∴ 1 magnet = 3/9 = $ 1/3 = 1:3
if the cost of 6 magnets is $2;
6 magnets = $2
1 magnet = 2/6 = $1/3 = 1:3
if the cost of 3 magnets is $1;
3 magnets = $1
∴ 1 magnet = $ 1/3 = 1:3
From the answers obtained, the equivalent ratio of 1 : 3 is the same in all case.
80.5 is the answer to this problem.
