If you look up "angles of 7 sided polygon" it would give a result of how many degrees polygons with 7 sides such as this one above would equal to. It's important to know that when finding x angles within.
7-sided polygons = 900 degrees in total
Since all the other angles except x are given, we can add all those up and set it equal to 900. So it would look like this:

Simply solve for x now.

So x = 111 degrees.
Hope this helps!
The horizontal distance from the helicopter to the landing pad is 1658.81 feet
<em><u>Solution:</u></em>
The figure is attached below
Triangle ABC is a rightangled triangle
A helicopter is flying at point A and landing pad is at point c
Angle of depression of the helicopter is 37 degrees so angle of elevation of this helicopter from landing pad will be same as 37 degrees
The helicopter is 1250 feet from the ground
Therefore, AB = 1250 feet
To find: horizontal distance from the helicopter to the landing pad
BC is the horizontal distance from the helicopter to the landing pad
BC = ?
By the definition of tan,


Thus the horizontal distance from the helicopter to the landing pad is 1658.81 feet
Correct answer:
"<span>D. As speed increases, height increases."
The x-axis is the one that indicates speed. The y-axis is the one that indicates height. As points of the represented line on the graph get bigger as to their x coordinate, they also get bigger on their y cordinate. When x increases, y increases also. This shows that their is a proportional relation between both the speed and height.</span>
