Supplementary means the 2 angles add up to 180 so...

124+(2x+4)=180

124+2x+4=180

124+2x+4-4=180-4

124+2x=176

124-124+2x=176-124

2x=52

2x/2=52/2

x=26
plug in and check

124+2x+4=180

124+2 (26)+4=180

124+52+4=180

176+4=180

180=180

Arada [10]

Idk if you are talking about independent and dependent variables but if you are then the independent variable is the variable that is changed or controlled and the dependent variable is the variable being tested and measured in a scientific experiment. Hope this helps!!!❤️
