(x) = x – 2inverse of the function
You can arrange it any way as long as you keep the 2 as the very first number
The height of the chimney above the floor of the observation deck is 52.4 ft
Two right angle triangle will be formed.
<h3>Right angle triangle:</h3>
Right angle triangle are triangle that has one of its angle as 90 degrees.
Therefore, using trigonometric ratio,
adjacent side = distance of observer from the bottom edge of the Delaware River drawbridge observation deck
Therefore,
tan 40 = opposite / adjacent
Where
x = height of the observer to the top of the observation deck
tan 40 = x / 200
x = 200 tan 40
x = 167.819926235
x = 167.82 ft
tan 30 = opposite / adjacent
y = height of the observer to the bottom of the observation deck
tan 30 = y / 200
y = 200 tan 30
y = 115.470053838
y = 115.47 ft
The height of the chimney above the floor of the observation deck = height of the observer to the top of the observation deck - height of the observer to the bottom of the observation deck
The height of the chimney above the floor of the observation deck = 167.82 - 115.47 = 52.35 ft

Answer:
No the ramp doesn’t meet the law. The slope is 4/50 which is 1/12.5
The slope of the ramp doesn’t meet the law because it’s slope is greater than 1/12. To adjust the ramp so that it meets the law, you could increase the height and/or the horizontal length to increase the slope so it is less than 1/12.
Step-by-step explanation:
