Question 1150836
<br>
Think of the sides of the triangle as three sticks.<br>
Two of the sticks have lengths 4 and 3.<br>
The total length of those two sticks is 7.  If the third stick has length 7 or more, then the three sticks can't form a triangle.<br>
So for the three sticks to form a triangle the length of the third stick must be less than 7.  Since the problem asks for the largest whole number length of the third side, the answer is 6.<br>
