Answer:
see below
Step-by-step explanation:
Add 4 to find the solution:
z ≤ 7
The value 7 is included in the solution set, so there will be a solid dot at that point. Numbers less than 7 are also included in the solution set, so the number line will be shaded to the left of that solid dot.
Using the Pythagorean Theorem we can solve.
20^2 - 12^2 = X^2
400 - 144 = X^2
256 = X^2
X = √256
X = 16 feet.
The answer is D.
