Question

What is the range of possible sizes for side x?

Answer 1

1.6 < x < 9.6

Explanation:

The range of possible sizes for side x is 1.6 < x < 9.6.

Answer 2

1.6 < x < 9.6.

Explanation:

Now x cannot be less than 5.6 - 4.0 = 1.6 as a triangle could not be formed if it were.

In fact x must be greater than 1.6.

Also x must be less than the sum of the other 2 sides.

So x must be less than 4.0 + 5.6 = 9.6.
