z° = 80° (Being corresponding angles)
y° + 80° = 180° (Being linear pair of angles)
=> y° = 180° - 80°
=> y° = 100°
x° = y° (Being interior opposite angles)
=> x° = 100°
|x+8|=5
then x+8= 5 or -5
then x= -3 or -13
we have

we know that

and

substitute in the expression



therefore
<u>the answer is</u>

$$$$$$$$$+$$$$=13 $ this is one way
If you graphed the equation: y = 5
You would put a straight line going horizontally through 5. Like this picture shows. If it were x = 5, for example, then it would go up and down through 5.
Let me know if this helped! Have a nice day!
