2.) Find the value of each trigonometric ratio:​

SinA = 40/50

Step-by-step explanation:

I think it's just asking if you understand the trig ratios. You aren't really solving for anything.

SinA is 40 over 50 because 40 is opposite of <A and 50 is the hypotenuse.

Then, use the trig ratios to figure out the other problems.

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.
