To the nearest foot, it would be 23 feet. I found this using the Pythagorean Theorem of a (squared) + b (squared) = c (squared). If you have 24 as the hypotenuse, you have to square this and subtract 64 (8*8) from it. That will equal 512. So you have to find the square root of that which is 22.62, which will round to 23 feet.

I am Lyosha [343]

Answer:

-170

Step-by-step explanation:

First, you would substitute 2 and 4 for a and b. 4 times 2 + 3(4 - 62) - 2 times 2 = ?

Then, do 4 times 2 (8), 3(4-62)=3(-58)

8 + -174 - 4 = -170

      Hey There!! (❁´◡`❁)

  1. The answer to this is: Map Key. Because, Large scale maps are typically used to show site plans, local areas, neighborhoods, towns etc. ... A 'small' scale map is one in which a given part of the Earth is represented by a small area on the map. Small scale maps generally show less detail than large scale maps, but cover large parts of the Earth.    
  2. The answer to this is: North. Like the wind rose, the compass rose was coincidentally designed in a fashion that resembled the rose flower. It helped to orient a map in the proper reading direction and gave the relative directions for certain points on the chart. Before compass roses were used on maps, lines were drawn from central points.
  3. The answer to this is: Map. Because, a Map help you to find places where you need to go.
  4. The answer to this is: Map Key. Because, A map usually has a legend, or key, that gives the scale of the map and explains what the various symbols represent. Some maps show relief, or changes inUsedLess elevation. A common way to show relief is contour lines, also called topographic lines.
  5. The answer to this is: Blue. Because Blue Water is mostly associated with the color blue. Uncolored versions of these symbols can be found in Earth, Air, Fire and Water Symbols.
  6. The answer to this is: Help you find directions: Because, A compass rose, sometimes called a windrose or rose of the winds, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points.
  7. The answer to this is: A system of vertical and horizontal lines. A grid system on a map is usually square and is represented by drawn lines on the map creating those squares. The purpose of the grid system is to give each point in the map an identifier, an address, by which we can refer to it by.
  8. The answer to this is: Map key Title, date, author, and sources usually appear on the map though not always together. The map's title tells what the map is about, revealing the map's purpose and content. For example, a map might be titled “Political Map of the World” or “Battle of Gettysburg, 1863.”
