Question:8 Please help, I have no idea.

Answer:
Option D is correct. i.e. Molly's street is perpendicular to Sophia's and Cole's street and is equidistant from Sophia's and Cole's houses.
Step-by-step explanation:
From the figure it is clear that
It is observable that Molly's street is perpendicular to Sophia's and Cole's street and is equidistant from Sophia's and Cole's houses.
As it clear from the figure that Molly's street cuts the Sophia's and Cole's street at the middle point.
So, the length of XZ is equal to the length of YZ.
i.e. [tex]XZ = YZ[/tex]
Therefore, option D is correct. i.e. Molly's street is perpendicular to Sophia's and Cole's street and is equidistant from Sophia's and Cole's houses.
