Get size of cathetus/i from size of hypothenuse and also proportion in between catheti?
Just how can I compute the size of the cathetus in a triangular if I recognize the size of the hypotenuse and also the proportion in between both catheti?
As an example :
The hypotenuse is $5$cm long, and also the proportion in between the catheti is $4:3$ - how much time are the catheti or either cathetus?
You can call one cathetus 4 *x *, the various other 3 *x *, and also use Pythagora's theory : (4 *x *) 2 +(3 *x *) 2 = 5 2 .
You will certainly get 25 *x * 2 = 25, which generates x = 1. So one cathetus is 4cm, and also the various other 3cm.
(Remember that 3,4,5 is a Pythagorean three-way)
