Iso confused number 10 is my set up right? idk

Close, but not quite right.

If you let x represent the measure of angle C, then, as you have, the measure of angle B is 3x+2.

The sum of angles B and C is 90, so the setup is ...

... (3x+2) +(x) = 90

... 4x = 88 . . . . . . . . . . collect terms, subtract 2

... x = 22 = m∠C

... 3x+2 = 68 = m∠B

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
