I dont know what the error is.

Question

double computeAngle (double a, double b, double c)
      angleA = acos ((b*b + c*c - a*a) / 2(b*c));
     angleB = acos ((a*a + c*c - b*b) / 2(a*c));
     angleC = acos ((a*a + b*b - c*c) / 2(a*b));
     }In this code im trying to To find the measure the angle in radians using the acos method of Java
i keep getting this ')' error and am not sure why. Also any help if im missing parts in that method.

Answer 1

Yup, it works perfect. Now only 1 other question. 'unexepected type'
in this line of code here.
     double computeDistance (int x1, int y1, int x2, int y2)
         int blah,blah2;
         (x1-x2)*(x1-x2) = blah;
         (y1-y2)*(y1-y2) = blah2;
     }i think what happens is im givin the x and y values at the end of the code for the user to input so im not sure if its recongnizing it as 0 or what not.
