1)
They are vertical angles so they are equal
2x+2=3x-52
-x=-54
x=54°
2)Supplementary angles adds up to 180
∠1+∠2=180
124+2x+4=180
128+2x=180
2x=180-124
x=28°
3) x and 43 making supplementary angles
so 43+x=180
x=180-43
x=137
and 43 and y are vertical angles so y=43
and same thing with x and z they are equal
z=137
4) 1st is neither
2)suppl.
