On Regents Exam
Posted: May 3, 2011 6:45 PM

There is a question using both the law of Sines and Cosines, and first you solve for a side and use it to find an angle. Say the side is an irrational number (ex. 10.254873209). Can a student round it to say the nearest hundredth and use it to solve an angle OR should a student use the 10.254873209 to solve the angle?

I have always taught students to use the number and not to round it until the end (the answer) but just wondered if that is allowed.
