What’s the answer and how did you find it ?

Since all triangle angles add up to 180°, you can set all the angles equal to 180.

(96 + 2x + (x + 12)) = 180

You can now simplify it together

108 + 3x = 180

Now you can isolate x by itself

180 - 108 = 72

72 / 3 = 24

x = 24

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
