Question

What is the range of possible sizes for side x?

Answer 1

Given:

The sides of the triangle are 2.8, 2.8 and x

We need to determine the possible sizes for side x.

Values of x:

The possible values of x can be determined using the triangle inequality theorem.

Applying the theorem, we have;

$x=2.8-2.8=0$

Thus, one of the possible value of x is 0.

Also, applying the same theorem, we have;

$x=2.8+2.8=5.6$

Thus, the other value of x is 5.6

Hence, the possible values of x are $0$
