Answer 1

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 :)
