# How to improve the accuracy of a test watch

1. I am measuring the angle of a string held at two points with a weight on it. Imagine tyiny a string loosely at 2 ends, and then putting a weight on it in the middle so it hangs down a bit like a 'Y'. I am measuring the and between the \ and / of the Y (Basically were the word and it). So how would i improve the accuracy? Someone said use a higher precision protractor?

Measuring the lengths of the arms of the Y and the seperation between the two arms and using the Cos Rule?
