Answer:
22 in < third side < 48 inches
48 inches is not a possible side length
Explanation:
The triangle inequality allows the third side to range between the difference and the sum of the two given sides:
(35 -13) < s < (35 +13)
22 < s < 48 . . . . . . inches
A side length of 4 feet (48 inches) does not satisfy the triangle inequality.

Additional comment
Some authors allow the "or equal to" case in the triangle inequality. When the sum of the shortest sides is equal to the longest side, the triangle looks like a line segment: it has an area of zero. Other authors prefer a strict inequality, so the triangle has non-zero area. That is the version we have used to answer this question. YMMV
