it doesnt matter, I just have to find x according to my teacher @Zale101

zale101 · Answer

A triangle will always have its interior angles added up to 180 degrees.

zale101 · Answer

Correct?

arivillafana · Answer

okay, yes. But I still forgot how to solve for x...

zale101 · Answer

Don't worry about solving for x now. First, look at what a triangle's interior angle has to add up to.

zale101 · Answer

See what angles are we giving.

zale101 · Answer

A+B+C=180 degrees interior angles total.

arivillafana · Answer

okay...

zale101 · Answer

$A+B+C=180 $

After plugging A=70, B=30, and C=x, we will get:

$\Large70+30+x=180 $
