Answer:
5/36
Step-by-step explanation:
We need the least common denominator for 12 and 9.
12 = 2^2 * 3
9 = 3^2
LCD = 2^2 * 3^2 = 4 * 9 = 36
11/12 - 7/9 = 33/36 - 28/36 = 5/36

Let x be the third side of this triangle. We can't find a single value for x because x can range between a boundary of values. The interval for x is
38-25 < x < 38 + 25
13 < x < 63
So as long as x is between 13 and 63 (ignore the endpoints themselves), then we have a valid possible third side length. The values that fit this description are...
14, 17, 19.4, 46
which are the answers
the other values (13, 63, 71) are outside of the interval mentioned
