What is the measure of y

y = 156 degrees

Step-by-step explanation:

90-66=24

180-24= 156

y is 156°.

Step-by-step explanation:

We know ∠FED is 66°, and ∠FED & ∠DEB (or z) equal 90° degrees. That means ∠z is 24° degrees as is ∠x, since it is adjacent to ∠z. ∠x and ∠y are supplementary, which meant they equal 180°. Subtract 24° (∠x's measurement ) from 180° to get your final answer of y being 156°.

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.

step-by-step explanation:

where is the question is there is a formula or is there not one
