It is possible to have a triangle with those lengths
<h3>
Answer: Bottom left corner (southwest corner)</h3>
![(4, \infty)](https://tex.z-dn.net/?f=%284%2C%20%5Cinfty%29)
The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"
The right endpoint is positive infinity. We always use a parenthesis with either infinity since we cannot reach infinity
The interval from 4 to infinity is written as
which is like saying ![4 < x < \infty](https://tex.z-dn.net/?f=4%20%3C%20x%20%3C%20%5Cinfty)
