What is Pythagoras triplet?
It's a set of three numbers that could be the lengths of the sides of a right triangle. In order for them to work that way, the squares of the two smaller ones have to add up to the square of the largest one.
How To Work Out The Area Of A Trapezium?
Area = 0.5*(sum of parallel sides)*height There also is a little rhyme to help you remember that i leanreed in year 7: half the sum of the parallel sides times the distance between them thats the way that i found out the area of a trapezium; sung in the way of the pied piper song.
How long must a ladder be to reach the top of a 13 foot?
This isn't hard to figure out if you know how far you want the base of the ladder from the wall. All you have to do is use the Pythagorean Theorem. The theorem is A2 + B2 = C2. A and B are the short sides and C is the hypotenuse (the side opposite the right angle). When dealing with a ladder, the ladder is the hypotenuse, or the C in the equation. Another way to put the formula is to multiply A by itself and B by itself, add them together, then take the square root of the result. Decide how far you want the base of the ladder from the building. Multiply that by itself then add that to 169 (that is the square of 13). Then take the square root of that and you get the ideal ladder height. Lets assume 5 feet from the wall. The square of that is 25. 169 plus 25 gives 194. The square root of 194 is 13.928, and we would round up to 14 feet. If you mean a step ladder, and you are trying to reach a ceiling, then you would need roughly the height of the room minus your own height. You might want to add a tad more. You could make it shorter, but that would not be wise, since you should always avoid the top two steps if possible.
