A 30 foot long ladder is leaning against an embankment incline 64° to the horizontal line as shown in the figure below. If the angle the latter makes with the ground is 40°, what is the distance from the top of the ladder down the embankment to the ground? Round to the nearest hundredth of a foot.

answer is. c

Do you have the photo?

The answer would be c.

The highest point of a hill (or mountain) is a single point.
a single point can only be precisely marked with a dot. 
putting on a contour line is impossible  on a single point because the contour line is created after multiple points that have the same hight are marked, and after that, all of those points are connected with a line that creates a closed area. so the highest point, as said above, is a single point, there are no other points with the same height, so the only possible way for it to be marked is with a dot, and there is no possibility for a contour line.
