Answer:

x=35

Step-by-step explanation:

The sum of angles in a triangle is equal to 180. In the triangle given, we have to add all the angles to find x.

So,

[tex]3x+x+40=180[/tex]

to find x, we must isolate it:

combine common terms:

[tex]4x+40=180[/tex]

subtract the 40 to both sides:

[tex]4x+40-40=180-40[/tex]

divide by three to isolate the variable:

[tex]4x/4=140/4[/tex]

and the resulting would be our x:

[tex]x=35[/tex]

to check if our answers make sense, substitute.

[tex]3(35)+35+40=180[/tex]

solve:

[tex]180=180[/tex]

that's it! hope it helps :)
