Answer:
1- b= 148 (180-32)
2- b= 76 (180-104)
3- b= 123 (180-57)
4- b= 83 (180-97)
5- x= 51 (180-78= 102) (102/2=51)
6- x= 46 (180-140= 40) (40+6=46)
7- x= 27 (180-108=72) (72-18=54) (54/2= 27)
This one is a bit longer:)
8- x= 28 (2x+4x+3+9= 180), (6x+12=180), (180-12=168), (168/6= 28)
Hope this helps! :)
