A hiker is lost in the forest, but has his cell phone with a weak signal. Cell phones with GPS can give an approximate location through triangulation, which works by giving distances from two known points. Suppose the hiker is within distance of two cell phone towers that are 21.4 miles apart along a straight highway (running east to west, double-dashed line). Based on the signal delay, it can be determined that the signal from the hiker's phone is 14.6 miles from Tower A and 10.7 miles from Tower B. Assume the hiker is traveling a straight path south reach the highway quickly. Required:
a. How far must the hiker travel to reach the highway?
b. Draw the figure and add the lengths to your diagram.
b. Draw the the distance the hiker must travel directly south to reach the highway.
c. Determine the distance the hiker must travel to reach the highway.
