Draw a right triangle to represent the problem.
The vertical height of the triangle is 9 ft, and it represents the tree.
The horizontal length, at the bottom of the tree is ground level and has a length of 13 ft.
Let x = angle of elevation.
By definition,
tan x = 9/13 = 0.6923
x = arctan(0.6923) = 34.7 deg. = 35 deg (approx)
Answer: 35°

28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0

Step-by-step explanation:
<em>The question has mission options; However, the question is still solvable.</em>
Given


Required
Determine possible ordered pairs of A to B
A function is of the form (x,y)
Let A be the range of the function and B, the domain
Let (x,y) be a function of A to B, where x represents any of the values in A sets and y represents any of the values in B
A ordered pair can only be regarded as a function if and only if it has unique y-values
Hence, a possible ordered pair is:

Another possible ordered pair is

<em>Note that there as as many as possible ordered pair as long as the y-values are unique</em>
