The horizontal distance from the base of the skyscraper to the ship is 870 feet.
Data;
- Angle of Depression = 45°
- Observation Deck = 870 feet
<h3>Horizontal Distance </h3>
To calculate the horizontal distance from the base of the skyscraper, we can use trigonometric ratio SOHCAHTOA here;
Since we have the value of angle and opposite, we can calculate the adjacent using tangent of the angle.
Let's substitute the values and solve
The horizontal distance from the base of the skyscraper to the ship is 870 feet.

So, at the beginning there are a total of 25*3=75 siblings (we can assume that each of them had exactly 3 siblings, that's what average means; that we can assume this).
Now we have 25+1=26 students and the number of siblings is 75+8=83
and the average is
, and rounded it's 3.19.
14-(25/P)
