Okay finally i shall blog in a new way now.
People are always so fixed, dead just like the Pythagorean theorem. It states that in any right triangle, the area of the square whose side is the hypotenuse (the side of a right triangle opposite the right angle) is equal to the sum of areas of the squares whose sides are the two legs (i.e. the two sides other than the hypotenuse).
If we let c be the length of the hypotenuse and a and b be the lengths of the other two sides, the theorem can be expressed as the equation.
Therefore C2 = A2 + B2
Then i have this uber noob maths question that i can get the answer easily. Hypotenuse is 17. While one is its side is 8. Then im required to find the unknown.
Using the formula,
C2 = A2 + B2, 17x17 = 8x8 + x2
x2 is 225
x is 15
Okay that's using the fomula. But its kinda weird because, 17, the hypotenuse is derived already. Which also means (i think) 17 is already squared.
And so
8x8 + x2 is 17 (C2)
BUT then x2 will be equals to -47 which is unsolvable
The above cant be solved and it is completely different because i THINK that 17 is C2, not C itself. But i know im definitely wrong cause Pythagoras is a basket.
Can anyone explain -.-
Anyway math test tomorrow, i shall practice more on it and NOT be so confident. (i think i am -.-) Anyone reading can call me for a chat ^_^
Oh yes another question. A square with the hypotenuse of 20. Find the area. Yes no dimensions to the sides. -.- Wtf and this is a primary question.
