It depends on a number of things: one is the distance of the arm, another is the expense of improving the accuracy, yet another is the cost of getting it wrong.
To explain, an error of 1 degree, across the length of a page will probably not be noticed. But a 1 deg error, when locating a star, for example, means that you will miss it by light years.
You can always increase the accuracy - use finer instruments, take more time etc. But will it all be worth the additional accuracy?
If you are doing a drawing to put up in your room and a line that should be vertical happens to be 89 degrees, well, does it really matter? But if the same error was made in an architect's drawing for a skyscraper (and acted upon), I would not like to live in that building!

How do measure an angle with a ruler?
You should use a special device for measuring angles - a protractor. With a ruler, it is much more complicated, but still possible: you can mark two points on the angle, one on each side; measure the distance from the vertext of the angle to those points; measure the distance between the points; then use the Law of Cosines to calculate the angle.
Why is accuracy so important when measuring ingredients?
Because if you add to much of that ingredient Like for example you add to much milk to pancakes it would be super watery so that is the reason why to be accurate ;D
