right angle math question

[jgr]

Ok since I've been out of school for quite some time, my math skills are not what they used to be. What is the formula to figure the sides of a right triangle given the hyp. and the angles.

. .......... 60
. .......... |..\
. .......... |.... \ side=40
. .......... |...... \
. .......... |........ \
. .... 90 ._____ 30

need to know the lenght of the other two sides

Ok you young bucks, don't let me down

Draw it and then measure? (Believe it or not, sometimes i did this)
Ok trig freaks, now's your spotlight chance.

You can do it in several ways.

One of them is COS/SIN. You choose one of the angles 30 or 60 (formed by a catet and the hypotenuse, which is the size measuring 40).

The opposite catet measures 40 * SIN(30)
The next catet measures 40 * COS(30)

Btw, I'm on two beers, this may be completely wrong. But I know how to do it, I promise :lol:

where a is the hypotenuse:

30-60-90 right triangle? are you peeps mad! theres a simple formula for this

Code:

shortleg = hyp / 2
longleg = shortleg * sqr(3)

i hope thats right....

uhh dude...that's pretty much what I just posted.

It won't always be a 30,60,90 though. That was just an example.

give another example then =\

try this

hyp =32
angle 33,57,90
