45 degree slope feels practically vertical when skiing, there are very few slopes this vertical on any in-bounds ski hill in the world. So this sounds like an academic question probably for a high school physics class? Just do the math and calculate top speed at 1/2G over 1500 feet. Just off the top of my head though, What in physics they call the guesstimate to check your work from being way off, i think I could easily exceed 50 or 60 mph skiing a 45 degree chute with no turns over 1500 feet.

### How do I miter with my radial arm saw (RA-2500). I can't tell from the manual.

the slide can be angled by the degree plate where the timber sits
the blade can be angled by the degree plate on the arm that mounts the saw
so you can get a 45 degree to the timber length and a 45 degree angle cut to that angle to give you a corner mitre cut

### Question. a triangle with two sides 1700mm each with a 45 degree angle. what will the length be of the third side?

If 2 angles are 45 degrees, the other must be 90, so Pythagorus' Theorem applies, so it is sqrt ( 1700^2 + 1700^2 ) = 2404.16
or
for triangles, a / sinA = c / sinC so c = ( 1700 / sin (45) ) * sin (90) = 2404.16.

### For a 10ft radius octagon, how long should each side be?

There is probably a formula for this or other ways of doing this, but I will give it a shot.

An octagon has 8 sides (octopus has 8 legs). To make an octagon, we effectively have 8 triangles joined at the centre. In the centre, we have 8 equal angles. Since a full circle is 360 degrees, each of these angles must be 360 / 8 or 45 degrees.

Now we can just focus on one of these triangles. We have an angle of 45 degrees at the centre and two arms extending out 10 feet.

At this point, we can use the cosine law to calculate the length of the side or we can recognize that it is an isosceles triangle and work out the other angles and determine the length of the side.

Using Cosine Law, a^2= b^2 + c^2 - 2xbxc Cos A
In this case, A = 45 degrees, b = 10 feet, c=10 feet.

Good luck.

Let me know if you have any questions.

### My Dept56 animated ski mountain. The skiers seem to heavy for the magnets in the ski run

Cut the friction on the skis or ski slope, use wax or soap to cut down on friction

### What is more difficult, sit-down hydrofoil or water-skiing?

Clearly, water-skiing is a more difficult sport for the reason that the water-skier rides on the water itself, while a sit-down hydrofoil rider rides underneath the water, which decreases the friction level substantially.

### A rectangle is 87 feet by 136 feet. find the length of the diagonal and the angles that it makes with the sides.

Length of diagonal =SQRT(136^2+87^2)=161.4465856 ft
One angle = arctan(87/136)=32.60... degrees
Other angle= 90-32.60=57.39 degrees

### I just bought a new Panasonic TX-P46S2 46"plasma

Try some adjustments. Brite changes the level of bright and Picture changes contrast. Less contrast and less brightness to even things out may help, and you won't be driving the panel so hard, so It's life will be longer too.

### I am going to put pea-stone all over a sloping hill .. How do I stop the pebbles from all landing on the bottom in a pile?

That depends entirely on the pea gravel and the slope of the hill. Read the Wikipedia entry on "angle of repose". Pea gravel typically has an angle of repose of 45 degrees or less. If you hill is less steep than 40 degrees you will probably be OK. Otherwise, you would need some retaining walls to reduce this angle. (Probably not what you had in mind.) Best thing to do is go to the source of your pea gravel and measure the slope of the pile it's in. This will be the maximum angle of repose for that material. Compare this to your hillside. If the hillside is at least 5 degrees less steep, you should be OK, unless you will expect foot or vehicle traffic on the pea gravel - in which case you would need at least a 15 degree margin.

### I need an urgent help..pleassssssssseeeee....

Given AC = 2675 feet
ð XAC= 14 degree
Therefore ð ACB = 14
Now Sin C= AB/AC
AB = AC . Sin C
AB = 2675 * Sin 14 feet
AB = 2675 * 0.241922 feet
AB = 647.1411 feet

might try

(54tan)/45

I don't have a calc that will do it or I would try it and see.
