i thought it's steeper than that

no yeah i know, i just thought bigger jumps tended to be a bit steeper than 35. i dont know/remember at all though, i was just saying i was under the impression that landings were steeper than that

yeah come to think of it 45 seems sort of steep

i think it would be fun on a really poppy step-over, but on a regular jump that's a little steep

really?
i always thought they would be built like a spine almost. like REALLY steep take-off and a really steep landing
oh well

the landing angle depends on the kind of jump, speed, size, launch angle, distance and difference in height (a good stepup can even land perfectly on flat while step down will have quite steep landings ....)
in essence your landing should be a tangent to your flight trajectory, but in practical fashions, they're allways less steep since conditions may vary in the jump and you don't want to overshoot by a mile ....
this is a simplified drawing, ie. drag wasn't considered
let's say you build a table feature, so your takeoff and landing are on the same height, you can see that in theory takeoff and landing are equally steep....
for a stepup, let's say your jump is at 45°, the blue line, if you put your landing on x=60 distance and about y=28 high, you could have a flat landing and be perfectly fine
for stepdowns, lets take the purple graph, at x=55 , y= 45 is a cliffdrop, you can see, the further you jump, the steeper it gets, lets say your trajectory follows the purple graph, if you drop 45, you see that you have covered a distance of about 55 (x=110) and you're moving in a 60 ° angle, so in theory a 60° landing would be perfect....

There's a lot more friction on dry slope material than snow, and how long an in-run needs to be is dependent upon a person's weight and whether you want to be able to turn into it or if you are willing to just point it. That's more of a feel thing than a calculation thing.
honestly, not intended to offend you in any way, but if you don't know how to approach/calculate something like that, i feel like you shouldn't be designing/building dryslope jumps...
those things already are sketchy, add poor design/construction and it quickly turns into a death trap ....
anyways, if you have your dryslope, just time how long you do from point a to point b in a straight line, from there you can calculate your friction coefficient and consequentially your speed after x ft ....
if you have your speed after x feet, you can start designing a jump like i mentioned above, make sure you dont put it up too high on the hill, cause afterall everyones gonna "slide" differently and need to speedcheck it to find their personal drop-in point ....
