Answer: The answer is $7.84 but that’s not a choice so I would go with $7.83
Step-by-step explanation:
Answer:

Step-by-step explanation:
One property of parallelogram is that opposite angles have the same measure, so we can write down:

Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:

Solve the equations:

To check, add up all 4 angles and check if they sum up to 360 degrees:

And please ignore the fact that I cannot insert the degree sign :(
<span>39 & 16.5 = -22.5
30 & 12.4 = -17.6
28 & 10.4 = -17.6
19 & 10.3 = -8.7
23 & 11.2 = -11.8
if the values are y values you will subtract them from each other to get the numerical value and because they all go from a larger number to a smaller number the rate is a negative. if they were from a smaller value to a larger value teh rates of change would be positive.
