Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.
---------------------------------------------------------------------------------
Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
Ask in the comments below if you are not sure about something.
I hope that helps you! :D
2(y−4)=4
(2)(y)+(2)(−4)=4
2y+−8=4
2y−8=4
2y−8+8=4+8
2y=12
y=6 is correct answer.
Hope this helps!
Thanks!
