Research building codes for ramps such as wheelchair ramps, boat ramps, or loading docks. Choose a building code for a ramp and describe the relationship between the lengths involved using geometry vocabulary such as hypotenuse, adjacent side, and opposite side. Use right triangle concepts from this unit to find any unknown lengths and angle measures of the ramp. Be sure to identify the type of ramp. Discuss why there are building codes for ramps and how you think they are determined.

Best ResponseYou've already chosen the best response.0Which one of those ramps would you like to research?

Best ResponseYou've already chosen the best response.0I have the codes for wheel chair ramps. Wheelchair ramps: The ramp should be no steeper than one foot per inch of rise, rise should not exceed 30 inches, width must be at least 36 inches, and landings much be at least 60 square inches both at the top of the platform and in any directional transition. Handrails are required on ramps that rise more than 6 inches or any more than 72 inches long. Wheelchair ramps may be fabricated from any material, provided they do not allow water to accumulate and have enough tread to prevent slipping.

Best ResponseYou've already chosen the best response.0Awesome! So the entire ramp should not be over 30 inches high. dw:1444310730469:dw

Best ResponseYou've already chosen the best response.0How much do you think our rise should be?

Best ResponseYou've already chosen the best response.0If its 1 ft per inch of rise, it could be 30 ft.

sleepyjess

Best ResponseYou've already chosen the best response.0So you want the height to be 30 inches?

sleepyjess

Best ResponseYou've already chosen the best response.0Okay, so the height is 30 inches, and they have to have AT LEAST one foot of length per inch of height, which means at a minimum, we have a 30ft long ramp

Best ResponseYou've already chosen the best response.0so since I have those two values, couldn't I solve to find the other value?

Best ResponseYou've already chosen the best response.0Yes I do, thank you so so sooooo much!

Best ResponseYou've already chosen the best response.0No problem! Let me know what you come to as an answer for the hypotenuse :)

Best ResponseYou've already chosen the best response.0But I need an angle value...

Best ResponseYou've already chosen the best response.0I know since I have the adjacent and opposite sides I would use tan

sleepyjess

Best ResponseYou've already chosen the best response.0Well, we know that opposite is 30 inches, and adjacent is 360 inches (30ft *12 inches). So what operation (sin, cos, tan) would we use to find angle A?dw:1444311592484:dw

Best ResponseYou've already chosen the best response.0Yep, you're already ahead of me :)

Best ResponseYou've already chosen the best response.0Or call @freckles over because I'm confusing myself...

Best ResponseYou've already chosen the best response.0If I did this right it think it would be 85.2

sleepyjess

Best ResponseYou've already chosen the best response.0That sounds a lot more reasonable than what I'm getting...

anonymous

Best ResponseYou've already chosen the best response.0so if that's the measure of the angle, how would I go about solving it to find the hypotenuse? I've only dealt with one value being x when working with sin, cos, and tan.

sleepyjess

Best ResponseYou've already chosen the best response.0Okay, you have angle B, with that we can find angle A (4.8) dw:1444312183349:dw

Best ResponseYou've already chosen the best response.0We have theta now, so we can plug that in, \(\tan(85.2)=\dfrac{30}{360}\)

anonymous

Best ResponseYou've already chosen the best response.0wouldn't I plug in 4.8

sleepyjess
 one year ago
Best ResponseYou've already chosen the best response.0yes yes yes, you can use sin(4.8)=x/30 or cos(4.8)x/360

Best ResponseYou've already chosen the best response.0No problem! Thank you for refreshing my memory on sin, cos and tan :)

Best ResponseYou've already chosen the best response.0So I used cos and when I worked it out I got 368.56 would that be right?
