Answer:
Step-by-step explanation:
Since this is a test/homework, I'll give you a hint.
A triangle always is 180 degrees. If you add up all the sides, it should be 180.
A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.
Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.
Hope this helps!

Answer:
88
Discussion:
Order of operations has multiplication\division performed before addition\subtraction. So our equation is interpreted as
(y/8) + 19 = 30 => subtract 19 from both sides
(y/8) = 30 - 19 = 11 => multiply both sides by 8
(y/8) 8 = 8 * 11 =>
y = 88

Answer:
ok, but what does z in the equation equal? Since its a letter it has to equal to a number
No, it isn't. A polygon is a closed figure with 3 or more sides.
