Just tell me what the angle sum is for a straight line.
anonymous
  • anonymous
73+x=130

@alexeis_nicole Nice. Now she can copy the answer without understanding what just happened.

180?
anonymous
  • anonymous
i think thats it
anonymous
  • anonymous
Yes. So if the angle sum of a straight line is 180, then how would you find the angle beside 130

@ashishthomas7 so it's 57?
anonymous
  • anonymous
yup

NO

OH. THAT WAS EASY. I FORGOT ABOUT THIS LOL. Sorry guys.

@marcoduuuh What's the triangle property that allowed you to find that it was 57?

@ashishthomas7 Could you not give answers away and actually allow others to understand what's going on?

107?

Do you know the property, exterior angle of a triangle?
anonymous
  • anonymous
and now applying that angles in a triangle add upto 180 x+73+180-130=180
anonymous
  • anonymous
θ and 130 are supplementary angles. so to find θ we need to subtract 130 from 180. we also know that a whole triangle equals 180 degrees. so once we find θ, we are able to subtract our known valus within the triangle to find x :)

@ashishthomas7 Already taught you a faster way to solving it using exterior angle of a triangle. \[73+x=130\]

thats wat i used first.... @Azteck
anonymous
  • anonymous
That's why I said your name. Are you derping or something?
anonymous
  • anonymous
All you did was put out an equation without telling how you got it.
anonymous
  • anonymous
i aslo told that after i writing the eqn scroll upward and luk...
anonymous
  • anonymous
Stahp trollin @Azteck brah.
anonymous
  • anonymous
AND IT'S NOT THAT DIFFICULT. I UNDERSTOOD HOW THE EQUATION WAS MADE YOU DERP.
