Given the function, <em>f(x) = 3x + 6,</em> we can solve for f(a), f(a + h) and
by substituting their values into f(x) = 3x + 6. We will have the following:

<em><u>Given:</u></em>
<em>We are told to find:</em>
- f(a)
- f(a + h), and

1. <em><u>Find f(a):</u></em>
- Substitute x = a into f(x) = 3x + 6
f(a) = 3(a) + 6
f(a) = 3a + 6
<em>2. Find f(a + h):</em>
- Substitute x = a + h into f(x) = 3x + 6
f(a + h) = 3(a + h) + 6
f(a + h) = 3a + 3h + 6
<em>3. Find </em>
<em>:</em>
- Plug in the values of f(a + h) and f(a) into

Thus:


Therefore, given the function, <em>f(x) = 3x + 6,</em> we can solve for f(a), f(a + h) and
by substituting their values into f(x) = 3x + 6. We will have the following:

Answer:
2 meters
Step-by-step explanation:
We need to use trigonometry for this. The appropriate one would be tangent, which is (opposite side) divided by (adjacent side).
In this case, the opposite side of angle A is BC, which is 6 meters. The adjacent side of angle A is AB, which is the ground. Since we don't know its length, we call it x.
Now, we write:
= 6/x
To solve, we just multiply both sides by tan(x) and x:
x = 6/[tan(72)] ≈ 1.95 meters ≈ 2 meters.
Thus, the answer is 2 meters.
Hope this helps!
