The square root of a number always yields a positive as well as a negative value. The square root of 64 is 8 while the square root of 169 is 13. All that is left is to recognize the trick of positive and negative value.
Theres a website called triangle calculator and you put in three things wether its SSA or ASA or whatever and it gives you all the measurements. Good luck on your quizzes and tests :)
