Suppose that when you measured D, you measured the fence at a slight angle, rather than straight across. (If you wanted to exaggerate this effect, suppose you measured the length from one corner to the opposite corner.) How would this affect your final measurement of g (for each part) - would you overestimate g, underestimate it, or neither? Quantitatively estimate the magnitude of the effect if the angle we were off by was one degree. How much would the magnitude of the effect differ between the two parts? Explain.

You would overestimate G.

.8414 Length measured = Actual length

Explanation:

If you measure things at an angle you are creating a rectangle triangle and instead of measuring one of the sides, you are measuring the hypontenuse, this results in an over estimation of the length of the side, if you want to calculate the real length you would have to use the trigonometric functions, Sin 1=.8414, this means that multiplying your measurement by. 8414 will give you the real lenght of the side taking out the angle.
