Simplify
10x - 4x = 36
6x = 36
Divide by 6
Solution: x = 6
Add 65+57 and subtract it from 180 then you get the third angle
(k - 34) x 9 =72
k - 34 = 72/9
k - 34 = 8
k = 8 + 34
k = 42
Third, the graph decreases from left to right because if you plug it into a graphing calculator - you can see that the line is a straight line, and does not decrease or increase whatsoever
