Hmm I'm studying
If angle A is 30 and the hypotenuse is 25 what is sida a?
Math my one weakness
Guys come on I need help
I believe you are dealing with a cosine problem
That is assuming that side A is adjacent to the hypotenuse
If not then it is a sine problem
Just type in sine or cosine and you will get the formula.

I haven't done this math in ages so I'm sorry if I got the problem trope wrong.
*type
Erhh my knowledge stat isnt high enough
I'm better at history to an extent
sin(30) = a/25
plug sin(30) into a calculator and solve from there
Sine is opposite/hypotenuse. Cosine is adjacent/hypotenuse. Opposite and adjacent depend on which angle you are referring to. Thus given the angle and the hypotenuse, we see that Opp=sin(30 deg)*25 and Adj=cos(30 deg)*25. It is convention that angle A is opposite side a, meaning that a=sin(30 deg)*25.
Damn so many people smarter then me that's actually a good thing.

Sorry I could not explains things better
You did a great job @Mishimans. Dont sell yourself short. Your answer was far more concise and less cluttered,but lost no meaning. Something I need to practice.
Dear lord the real Mitsuru is here. Thank the lord I was worried for a second about well you know beds.
@-Labrys-
SOH CAH TOA?

Yeah I just kinda heard something about trash and a heap there.

@IamThou precisely. Simple geometry.
@Tatsuya
Since the Thot has been cleared, the true Mitsuru has been awakened.
@IamThou That guy will either help you or murder you... Probably murder from what I hear.
