If x is a positive integer, and two sides of a certain triangle have lengths 30 and 45 respectively, which of the following could be the length of the third side of the triangle?
I. 45
II. 75
III. 145	Choose the correct choice:	A) I only	B) II only	C) I and II only	D) II and III only	E) I, II and III
Following the triangle inequality rule, which states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides:   Difference of other 2 sides &lt; any side &lt; sum of other two sides. Let the third side of triangle be AB.   So, 45 - 30 &lt; AB &lt; 45+30,   and 15 &lt; AB &lt; 75   Check if any of the answers are between 15 and 75.   I: 45 ; could be a possible value.   II: 75 ; could not be a possible value.   III: 145; could not be a possible value.   I onlynswer :I only
