Pretty much the way I look at it, there is one angle, and 2 sides beside it. Easiest way for me to explain.
Total Numbers = 5
Mean (Average) = 85.2
Standard deviation = 10.70981
Variance(Standard deviation) = 114.7
Population Standard deviation = 9.57914
Variance(Population Standard deviation) = 91.76
1.87 is 8.5% of 22 so 8.5% of 80 is 0.085 x 80 so $6.80
Answer: 5
Step-by-step explanation:
Since 
, by the corresponding angles theorem, 
. This means 
by AA.
As corresponding sides of similar triangles are proportional,
However, as distance must be positive, we consider the positive solution, x=5.
Therefore, the answer is <u>5</u>
