D is the only viable answer among these, as A, B, and C all contain two even integers which, by definition, have a greatest common factor of 2.
<em>Correction: </em>I was incorrect in saying that <em>all </em>even integers have a greatest common factor of 2; 2 is at least guaranteed to be <em>one of the common factors </em>in any group of even numbers, but these examples all have it as their <em>greatest </em>common factor as well.

1/2 radian ≈ 28.648°
Multiply by 180°/π to convert from radians to degrees.
Sin 27=11/a
a=11/sin 27
a=24.2
The <span>Triangle Inequality Theorem establishes that the length of the triangle is shorter than the sum of the two lenghts of the others two sides. Then, you have:
a=6 (the lenght of a side of the triangle).
b=13 (t</span>he lenght of a side of the triangle).<span>
c=x (the length of the third side).
Therefore:
c<a+b
c<6+13
c<19
The lenght of the third side is:
(13-6)<c<19
7<c<9</span>
