Answer:

x=20

Explanation:

a line = 180 degrees

68+5x+12=180

80+5x=180

5x=100

20

Another way to solve it is:

180-68=112

5x+12=112

5x=100

x=20

Answer:

x= 20

Explanation:

The two angles form a straight line. Their sum is 180

68+ 5x+12 = 180

Combine like terms

80+5x= 180

Subtract 80 from each side

80+5x-80 =180-80

5x= 100

Divide each side by 5

5x/5= 100/5

x = 20
