Find the indicated side of the right triangle

x=9

y=9sqrt2

Step-by-step explanation:

Since it is a 45 45 90 triangle, the two side lengths are the same

But the hypoteneuse is always the side length time sqrt 2

9

Step-by-step explanation:

so to find x you have to use the tan ratio because x is the opposite of the angle at the top and you are given which is 9

tan45=opposite/adjacent

tan45=x/9

x=tan45×9

=9

I hope this helps

step-by-step explanation:

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.
