Jane is hiking at an elevation of 142 feet above sea level she descends 325 feet into a valley. what is janes Elevation in feet in relation to a second hiker who is 24 feet below sea level?

Given parameters:

Elevation of hiking  = 142ft

Descent of Jane  = 325ft

Height of second hiker  = 24ft below sea level

Unknown:

Jane's elevation relative to the second hiker = ?

Solution:

The sea level here is the reference plane and the elevation here is zero;

   Jane                     142ft                          142ft above sea level    

                                                                ↓ Descent

          Seal level        0ft                            0ft                                 Second hiker

                                                                                                              24ft

                                                                   183ft(below sea level)

The elevation of Jane in relation to the second hiker is 183 - 24 = 159ft below the second hiker.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
