c# - Calculate hypotenuse from height and angle -


i'm bit rusty on math department , want calculate hypotenuse of right angle triangle given height (h) , opposite angle (c).
right angle triangle
tried this:

 double = h / math.sin(v);

the whole code snippet:

string line; while ((line = console.readline()) != null) {     string[] split = line.split(new char[] { ' ' }, stringsplitoptions.none);     long h = int64.parse(split[0]);     long v = int64.parse(split[1]);     double res = h / math.sin(v);     console.writeline(res); }

however doesnt give me right answer. instance if height 10000 , angle c 89, hypotenuse should ~10001 ~11626. i've tried in javascript , c# same faulty answer, calculator gives correct answer. ideas of i'm doing wrong?

angle c must in radians not degrees

to radians use c * math.pi/180
