Answer 1

Why you add Math.cos()?
75° = 1.309.. radian.
Math.radian() convert degree to radian.

do this :
Math.toDegrees(Math.acos(radian));

you should rename your convert var to cosRadian

Answer 2

// cos(75°) = 0.258819 rad;
double radian = 0.258819;
int degree = 75;

double toRadian =
Math.cos( Math.toRadians( degree) );
System.out.println( radian +" = "+ toRadian);
// 0.258819 = 0.258819...

int toDegree = (int)
Math.toDegrees( Math.acos( radian) );
System.out.println( degree +" = "+ toDegree);
// 75 = 75

Answer 3

I need to calculate the values of the angles of the triangle.
According to the formula, I get the cos() value, which then, to convert to degrees, I need to look at the Bradis cosine table.
How do I convert this value to degrees?
