When parallel lines are cut by a transversal, which of these statements must be true about the measures of vertical angles? They are equal to each other, because one vertical angle is a reflection of the other.

They are equal to each other, because one vertical angle is supplementary to the other.

They are not equal to each other, because one vertical angle is not supplementary to the other.

They are not equal to each other, because one vertical angle is not a reflection of the other.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=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.
