You taught this so much better than geometry teacher did 2 years ago. My math teachers always find seem to find ways to make things more complicated than the truly are.
@@artistpolarbear1467 Because angle Z ( the one that is outside the triangle ) is an exterior angle to the angles Y and X( inside the triangle) " An exterior angle is an angle that is equal to the sum of the opposite interior angles ". Plus, if you simplified his answer Y + X + 180 - Z = 180, it will be Y + X - Z =0 Y + X = Z
kind of late but its 180-z because the angles are supplementary and have to add up to 180 degrees, like he showed in the begnnining of the video. 180-z will give what is required to reach 180.
that angle isn't z because they aren't vertical angles, they are supplementary angles, which means both the angles added up is equal to 180 degrees. But since we already know what z is and we know that both of them added together are 180 then we would take 180- z to get that missing angles degree. I think your only confused because of the first portion which is identifying and differentiating vertical and supplementary angles.

thanks been roaming the internet looking for a guy that doesnt take like years to get to the actual point THANKS :D

dude, you are the best teacher ever. hands down.
I don't know what I would've done without your videos. I hope you get everything that you want in life because you deserve it :-')
You are way more better than my teacher, thank you thank you.
THANK YOU SO MUCH !!!!! you’re an amazing teacher :)
you might now know it, but you really really helped me like no other person... Thank you.
my SAT is in less 2 hours :)
Same lmao glad to know I'm not the only one 😂
How did it went?
8:00
We can also say " Z = Y + X "
why though ?

I swear you helped me a lot I have to take Sats tomorrow , I've been scared this whole thinking I wasn't ready, thank you wish me luck
How'd you do? I'm a little worried for mine. I want a 2,200 + score. I'm still a sophomore and I still have time, but any tips and tricks?
This helped SO MUCH !!!
my math sat teacher sucks at explaining stuff . THANK YOU
Very nice
So for the last question, what is a+b?
60
Thank you!
on 7:57 , can someone explain why it was 180-z and not just z? is that because it was on the line and apart of the angle itself?
