By using what we know about right triangles, we conclude that the height is 11ft.
<h3>
How far is the top of the escalator from the ground floor? </h3>
We can think of this as a right triangle.
Where the length of the escalator is the hypotenuse
We know that the angle of depression is 42.51°, then the top angle of our right triangle is:
90° - 42.51° = 47.49°
Now, the height of the top of the escalator would be the adjacent cathetus to said angle, then we can use the relation:
cos(a) = (adjacent cathetus)/(hypotenuse)
Replacing what we know:
cos(47.49°) = height/16ft
cos(47.49°) *16ft = height = 10.8ft
Rounding to the nearest foot, we get:
height = 11ft

Answer:
the answer is no
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.

I hope this is right and if it is not then I'm sorry.
Answer: The answer is one-twelveth.
Step-by-step explanation: Given that we have a 32 feet fence around a square garden ABCD as shown in the attached figure.
There are four equal sections AB = BC = BD = DA of the fence.
If we paint one-third of one section, then we need to find what fraction of the total fence we painted.
Since ABCD is a square, so AB = BC = CD = DA = 8 feet.
Let we paint one-third of section AB. so, the part of AB we painted is
Therefore, the fraction of the fence that we painted is given by
Thus, we painted one -twelveth of the total fence.
