There is a weight of 254.8 Newtons hanging from two ropes. One rope makes an angle with the ceiling with 71 degrees, and the other rope makes an angle with the ceiling with 28 degrees. What is the tension in each rope (use triangle trig, again pic is located below)?

thanks in advance. I had 269N and 543N for the ropes, but I am not completely sure.

Okay. The problem is 9/2x+2=8/x.

(Nine over 2x plus two equals eight over x)

Please use the "fraction-buster" method and explain in understandable terms.

Have a nice day.

I have heard the banana trees are actually weeds. I never heard the full explanation, but something to do with the tree dying every year and a new one growing. Is that true?

There is a rope that has a weight of 147 Newtons hanging from it. The weight creates two 8 degree angles with where the rope was (straight line) and where it is with the weight on it. How much tension is in the rope (Pretend the rope is weightless, and use triangle trig to figure it out)? I had 1056N, but I dont know if it is 1056 or 528N. Here is a pic of what it would look like:

Everyone knows that when high heels are worn, they make a click-clock sound when the wearer is walking. My question is...

how come one click sounds different from the other? I tried stomping one foot at a time while I was wearing high heels, and no matter what, one foot has the click, and the other has the clock.

How come?
