Question

A triangle has two sides of lengths 7 and 9.what value could the length of the third side be?

Answer 1

13, 10, 8, 5

Explanation:

2+7=9 9=9 the requirment is it has to be greater than the third length not equal to

Answer 2

The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.

So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.
