Answer: x = 17.5

Step-by-step explanation:

All expressions for the angles as a whole must equal 180 because it is on a line.

so we need to set all the expressions equal to 180 then solve.

4x+2x+30+2x+10=180

combine like terms

(4x+2x+2x) + (30+10) =180

8x + 40 = 180

now subtract 40 from each side

8x=140

isolate the x by dividing each side by 8

x = 17.5
