a 215-N box is placed on an inclined plane that makes a 35.0 degree angle with the horizontel. Find the component of the weight force parallel to the plane's surface. can someone explain how to find the answer to this problem?

2cos*2x-cosx=1 find all solutions to the equation on the domain [0,2ð] i got ð/4, 7ð/4, 3ð/4, and 5ð/4 but only got two out of four points... what did i do wrong?

an airplane is flying at a constant altitude of 28000 meters. when first seen to the east of the observer, the angle to the airplane is 71.5 degrees. after 73 seconds, the angle of elevation is 51.6 degrees. find the speed of the airplane.

thanks so much!

a ski slope on a mountian has an angle of elevation of 25.2 degrees. the vertical height of the slope is 1808 feet. how long is the slope?

i tried doing that but my hypotenuse was smaller then my opposite... is that ok... sin(25.2)= .4257 then i divided by 1808 to get x by itself and i got... 2.3535 E -4 wouldn't that be wrong?
