Answer:
As worked out below
Explanation:
13) for x use the given equations and set it equal to 96 .. b/c that angle is complementary... well it's the same.. but in fancy math jargon.. sooo
6x+54=96
6x=42
x=7 nice
for y use that 180 is what the two angles add up to
y+96=180
y=84 so I think butterfly got that one right
14) for x use that the two angles together must be 180 b/c the M and N lines are parallel :)
9x+48 + 4x+54 =180
13x+102=180
13x=78
x=6 yay!
for y use that the lines are at right angles so it must be equal to 90
2y+34=90
2y=56
y=28 yay :)
