An obtuse triangle is formed if there is an angle that has a measure of more than 90 degrees. You can determine if an obtuse angle is formed by two sides of a triangle if it meet this condition:

Let a and b be two sides of a triangle and c is the longest side:
a^{2}  +  b^{2}  \ \textless \   c^{2}

So taking your given:

10^{2}  +  15 ^{2} < c^{2}
100 + 225   < c^{2}
325  <  c^{2}

To get the smallest possible number, just get the square root of both sides:

\sqrt{325} < \sqrt{c^{2} }
  18.03  < c

So your smallest possible whole number is 19
