Answer:
Angle of Depression and Angle of Elevation
One application of the trigonometric ratios is to find lengths that you cannot measure. Very frequently, angles of depression and elevation are used in these types of problems.
Angle of Depression: The angle measured down from the horizon or a horizontal line.
Angle of Elevation: The angle measured up from the horizon or a horizontal line.
What if you placed a ladder 10 feet from a haymow whose floor is 20 feet from the ground? How tall would the ladder need to be to reach the haymow's floor if it forms a 30∘ angle with the ground?
Answer:
Boxplot is constructed using quartiles and 5 No. summary means including minimum value of data, 1st quartile, 2nd quartile, 3rd quartile and maximum value of data.
As data already in increasing order, we find quartiles using the following formula,

where n = No. of Observations.
∴, 1st Quartile,

2nd Quartile,

3rd Quartile,

Minimum value of data = 32 & Maximum value of data = 99
So, Values of 5 no. that are to ne include in Boxplot are 32, 55.5, 69.5, 80.5, 99.
BoxPlot is attached with this ans.
