8)
rhombus, all sides are equal
so
6m - 12 = 4m+4
2m = 16
m = 8
VW = 6(8) - 12
VW = 48 - 12
VW = 36
XY = VW = 36
9)
3n^2 - 0.75 = 90
3n^2 = 90.75
n^2 = 30.25
n = 5.5
so
<YVW = 2(9*5.5 +4) = 2(53.5) = 107 degrees
10)
<VYX = 1/2(360 - 2*107)
<VYX = 1/2 (360 - 214)
<VYX = 1/2 (146)
<VYX = 73 degrees
11)
<XYZ = 1/2 (73) = 36.5 degrees
