Answer:

x=15

Step-by-step explanation:

the angles are supplementary meaning that they will add up to equal 180 so we write the equation

6x+10+4x+20=180 and solve for x

step 1 combine like terms 6x+4x =10x and 10+20=30

10x+30=180

step 2 subtract 30 from each side

10x=150

step 3 divide each side by 10

x=15

Step-by-step explanation:

if the lines are parallel it means they are equal so,

6x+10=4x+20

6x-4x=20-10

2x=10

2x=10

2 2

x=5

6(5)+10 4(5)+20

30+10 20+20

40 40

it means the answer is 40
