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.

3)complementry
