For question 9 - It is stating that AE is equal to 38. So the length of the entire line is 38. We then need to look at which figures are actually useful to us, which in this case is AC which is 10. Therefore the answer is as simple as 38-10, which gives us an answer of 28 for the other half of the line, notated as CE.
Whether it can be equal to that value. For example, if 5 is greater than x, then an open circle will be useful. If 5 is greater than or equal to x, a closed circle will be used.

Answer: c)
Step-by-step explanation:
This can be done through trial-and-error. Use the pythagoreas' theorem 
and if the left side of the equation is equal to the right, that is the answer.
