Explanation of Solution
Given:
The one unit represents the one mile, the location of the caller is determined to be 50 miles from the tower of the origin.
The person is 40 miles from a tower at (0,30) and 13 miles from the tower
Calculation:
The distance of the caller from the tower at the origin by the distance formula is,
Consider the distance of the caller from the tower of the point (0, 30) by the distance formula as,
Consider the distance of the caller from the tower of the point (35, 18) by the distance formula as,
Subtract the second equation from the first as,
Substitute
Thus, the solution for the equations
Substitute the points in the equation
Also,
Thus, the exact location is
