Question

A surveyor is surveying a street. The surveyor is standing at point C looking down the street at no parking sign at point D and a stop sign at point R. Given CD = 6x-8 meters, DR = 4 meters, and point D is between C and R, what is x in meters?

Answer 1

2

Explanation:

If point D is between C and R, then the vector CD = DR is true. Given the following parameter CD = 6x-8 meters, DR = 4 meters, to get the value of X we will equate both vector functions as shown;

6x-8 = 4

add 8 to both sides

6x-8+8 = 4+8

6x = 12

divide both sides by 6

6x/6 = 12/6

x = 2

Hence the value of x in metres is 2 metres.
