Answer: 1, 2, 5
Step-by-step explanation:
The first equation is true because angles in a triangle add to 180 degrees.
The second equation is true because both sides equal 180 degrees (left hand side is a straight angle, right hand side is the sum of angles in a triangle)
The third equation is not true because z = 180 - y, and 180-y+w+z is not 180.
The fourth equation is not true because z=180-y, and 180-y=w+y is not always true.
The fifth equation is true by the exterior angle theorem.
A is 7 & 7/8. B is correct. C is 1 & 1/4. They are all in simplest form, also.

Answer:
x = -8, 1
Step-by-step explanation:
Hi there!
Move 8 to the other side:
Now, we can ask ourselves: what two factors of -8 add to 7? Those two numbers would be 8 and -1. Knowing this, factor:
Because of the zero product property (that states that if the product of two numbers is 0, then one of the numbers must be equal to 0), we can find the solutions to the quadratic by setting each term equal to 0:
Therefore, the solutions of the quadratic are -8 and 1.
I hope this helps!
