AC = 39
This means that AB + BC = AC
2x - 8 + x + 17 = 39
3x + 9 = 39
3x = 30
x = 10
Then, insert the x into both AB and BC.
AC = 2(10) - 8
AC = 20 - 8
AC = 12
BC = (10) + 17
BC = 27
19.
DG = 60
4x - 3 + 2x + 21 = 60
6x + 18 = 60
6x = 42
x = 7
DO = 4(7) - 3
DO = 28 - 3
DO = 25
OG = 2(7) + 21
OG = 14 + 21
OG = 35
