Difference in elevation are best shown using what?
On a map, the differences in elevation are best shown using contour lines.
What is the approximate height of a building when the angle of elevation at the top of a building is 34 degrees and at a point 80 feet closer the angle of elevation is 45 degrees?
It can be shown that:height = (d tan α tan β)/(tan α - tan β)where: α is the angle closest to the objectβ is the angle further away from the objectd is the distance from the point of angle α to the point of angle βThus: height = (80 ft × tan 45° × tan 34°)/(tan 45° - tan 34°) ≈ 165.78 ft
What is the highest elevation line shown on the map?
The highest elevation line shown on the map depends on what is the highest point - which is often the summit of a hill or mountain.
On a topographic map elevation is shown by means of?
Contour lines
What is the type of congruence between the triangles shown?
side- angle- side
what- Estimate the measure of the angle shown.?
90
Which is not a correct name for the angle shown?
bac
Which of these correctly classifies the angle shown?
perpendicular
What must be shown to be congruent in order to say that the triangles are congruent by SAS?
Two sides and the included angle of one triangle must be congruent to two sides and the included angle of the other.
Differences in elevation are best shown using a .?
topographical map.
What is the angle of rotational symmetry of the figure shown?
45
The elevation on a topographic map is shown using?
The elevation on a topographic map is shown using contour lines, which connect points of equal elevation. These contour lines help to visualize the shape of the land and provide information on the topography of the terrain. The spacing between contour lines indicates the steepness of the slope, with closer lines representing steeper terrain and wider spacing indicating flatter areas.
