One angle is 25 less than four times it's supplement. what is the measure of both angles?

Let the first angle be x and the second be y.

Supplementary angles add up to 180, so:
x + y = 180

Also, as given in the statement:
x = 4y - 25

Substituting into the first equation:
4y - 25 + y = 180
5y = 205
y = 41

x = 4(41) - 25
x = 139

One angle is 139° and the other is 41°.

b. A data table

Step-by-step explanation:

We say that it is not a scientific model because we don't know what the table shows and because the table contains information. This information hasn't been turned into something visual, that we can call a model.
