5 is the in its value bc its on the y intercept meaning the starting point
3 divided by (4 + n). Hope it helps! :)
-8 - 7x is the factored version.
X and Z equal 72
Y equals 108.
This is because y and 108° are vertex angles meaning they are both equal to each other. X is 72 because it’s form a supplementary angle with 108°. So what I did to find x is I subtracted 108 from 180 to get 72°. Then I know x and z are vertex angles meaning that z is also equal to 72°
