Answer:

x=48

Step-by-step explanation:

10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees

Get the variables together

10x-20+6x+8=180

-6x -6x

4x-20+8=180

add together -20 and 8

4x-12=180

add -12 on each side

4x-12=180

+12 +12

4x=192

divide all by 4

x=48
