# On a LED which leg is longer - positive or negative?

L.E.D has one leg longer then the other one, the longer one is positive and the smaller one is negative. If you have a l.e.d which has same length of legs then look inside the l.e.d for two kind of triangle peices and one of them will be smaller which is positive and one which is bigger and is negative.

### How do you find the side lengths of a 20-70-90 triangle?

There are an infinite number of different sets of lengths that will do it. You have to start by choosing the length of one side, and when you do that, here's how to find the others: Shorter leg = (longer leg) x 0.364 Shorter leg = (hypotenuse) x 0.342 Longer leg = (shorter leg) x 2.747 Longer leg = (hypotenuse) x 0.94 Hypotenuse = (shorter leg) / 0.342 Hypotenuse = (longer leg) / 0.94

### What does a plus and minus tattoo on the top of a leg symbolize?

there was a point of time in the early 80's when there was a trend of tattooing a + or - on yourself as an indication of if you were HIV + or HIV-. if some one who was negative became positive they sould just change the negative to a positive of get a positive tattooed next to it. however it could symbolize nothing and just look neat, or it could symolize something to the…

### How do you solve a 30-60-90 degree?

To solve a 30-60-90 triangle, you need to know the length of one side. The hypotenuse is twice as long as the shortest leg (the side opposite the 30 angle) The longer leg (opposite the 60 angle) is the length of the shorter leg times the square root of 3. So in summary: If you know the hypotenuse, divide it by 2 to find the shorter leg, and multiply that times the square root of…

### How long is a cows leg?

A cow's hind leg is typically longer than the front leg, just like our leg is longer than our arm. Leg length, however, depends on the frame size (which is height over width and depth of the animal, in a manner of speaking), and the breed. On average, the front leg of a cow is typically 24 to 30 inches long, and the back leg is 48 to over 50 inches tall. Taller cattle will…

### The hypotenuse of a right triangle is 4 inches long One leg is 1 inch longer than the other Find the length of the shorter leg?

Answer: 2.283882181 inches and the other leg is 3.283882181 inches Check: 2.2838821812+3.2838821812 = 16 and the square root of 16 is 4 This problem was solved by using Pythagoras' theorem and the quadratic equation formula. Pythagoras: Let the shorter leg be x and the longer leg be x+1. x2+(x+1)2 = 16 x2+x2+2x+1 = 16 X2+x2+2x+1-16 = 0 2x2+2x-15 = 0 Solving the above equation by using the quadratic equation formula will give: x = -3.283882181…

### A model builder wants to model a right triangular lot that has legs of 135 ft and 75 ft The model is to have its longer leg 4 inches longer than the shorter leg Find the dimensions of the shorter l?

The difference between the shorter leg and the longer leg is 60ft. In the model, this distance is only 4in. Multiply 60 by 12 to get the difference in inches, 720in Divide 720 by 4 to find that the model is 180 times smaller than the real thing. Multiply the shorter leg by 12 to convert it into inches, 75*12=900 Divide 900 by 180 and you will have the length of the shorter leg of…
