Answer: 26.8 feet
Step-by-step explanation:
In the figure attached you can see two right triangles triangle ABD and a triangle ACD.
You are located at point B and the other person at point C.
The approximate height of the lifeguard station is <em>x</em>.
Keep on mind that:

Therefore:
<em>For the triangle ABD</em>:
[EQUATION 1]
<em>For the triangle ACD:</em>
[EQUATION 2]
Solve from DC from [EQUATION 2]:

Substitute into [EQUATION 1] and solve for x:

≈26.8ft
Answer:
y < -x - 5
-4 < -(-3) - 5 = 3 - 5 = -2
So its point (-3, -4)
