To find the horizontal distance (run) needed for the ramp, we can use the Pythagorean theorem. In this case, we know the length of the ramp (hypotenuse) and the height of the ramp (vertical rise).
The relationship is given by:
Where:
is the length of the ramp (84 ft), is the height (unknown), is the horizontal distance (run) we want to find (4.8 ft).
Substituting in the values we have:
Calculating
Now, isolate
Now, take the square root of both sides to find
So the vertical height (rise) is approximately 83.83 ft.
Now we already have that the horizontal distance (run) is given as 4.8 ft, but if we are looking for confirmation or checking another set of calculations for the horizontal run based on these parameters while being different from wrong answers provided, we focus on the right approach.
However, from standard geometry and triangle ratios based on ramp run and height as mentioned, the derived run length will logically revert back to its provided length of 4.8 ft, albeit verifying through numerous rectifications is needed when numbers have been restricted on perceived wrong results.
If you need it rounded, defined as close to precision per underlying constraints, it stays at 4.80 for a formal check.
Hence, for formal feedback based on internal heights or deriving, these numbers lead to congruence based within provided data. Final attention might yield:
The rounded final run is
If the request suggests strict alternatives, aligning close numbers might yield insufficient divergence from stated limits.
Accordingly, please keep this as structured-based unless unique alternate run-distance affirmations are uniquely characterized.
