Find an angle between 0 and 2 pi that is coterminal with the given angle. the angle is10 radians

The question ask to determine and calculate the angle between 0 and 2 pi that is coterminal with the given angle, and the angle would be 10 radians and base on my calculation and further research about the said question, I would say that the angle is 2pi -10 radian. I hope this would help 

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
