we know that The triangular inequality establishes that: The sum of the lengths of any two sides of a triangle is greater than the third side therefore if a=3/4 in----> 0.75 in b=3 in c= third side of triangle (a+b) > c (3+0.75) > c 3.75 > c--------> c < 3.75 in so
the answer is the length in inches of the third side of the triangle must be minor a 3.75 in
