Can someone do this thanks and quickly:)

This figure is a quadrilateral, and therefore the sum of the interior angles must be 360°.  Adding them up, we get 40° + 128° + x + 82° = 360°, or

168° + 82° + x = 360°, or  250° + x = 360.  Subtracting 250° from both sides results in 110°, which is the measure of x.

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
