1
w
is required to build an accessibility ramp with a slope of How far
12
from the entrance will the ramp need to begin?

Answer 1

Answer: 11.3 feet

Step-by-step explanation:

The question is not structured properly but assuming the ramp should have a slope of 12 feet then this can be solved with the Pythagorean theorem.

a² + b² = c²

a is the height above the ground

b is the distance of the ramp's beginning from the entrance

c is the slope

4² + b² = 12²

16 + b² = 144

b² = 144 - 16

b² = 128

b = √128

b = 11.3 feet
