Answer:

x=35

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,


3x+x+40=180

to find x, we must isolate it:

combine common terms:


4x+40=180

subtract the 40 to both sides:


4x+40-40=180-40

divide by three to isolate the variable:


4x/4=140/4

and the resulting would be our x:


x=35

to check if our answers make sense, substitute.


3(35)+35+40=180

solve:


180=180

that's it! hope it helps :)
