Hey y'all, you mind me with this geometry problem, i'd really appreciate it : )

c

-by-step explanation:

it would be c

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

by definition every angles supplementary opposite by vertex are congruent
