Answer 2

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,

$3x+x+40=180$

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 :)
