Question

What symbol do I use and number line help plzz​

Answer 1

t > 90

open dot arrow heading to the right starting on 90

Explanation:

as t is above 90, we will use the greater than symbol (>), we cannot use = or < because they both indicate that it is either equal, or less than 90 which it is very much so not :)

Now the number line, as we know it is not
`\geq` (greater than or equal to), its only > (greater than) so it will be an open dot (which indicates it does not include the number it is above), and it will begin on the number 90, and head right as it is a number that can be anywhere above 90.
