#8 you do 360= 112+136+x... then you solve for x. X=112. Now you divide this by two since it is an inscribed angle. For #9 I have this very simplified work in the picture. Sorry I did not do #10
5/2

SLOPE: 3 Y INTERCEPT: 3
The other answer is not correct!!!
X = 4.33333333333
y = 5.33333333333
z = 6.33333333333
First you add 3 and 2 so that is 5 and then you subtract 5 from 9 so the answer is 4.
