Question

The team thinks the black bears are at the position of point F. The rangers use two-way radios to communicate with one another. The radios from the ranger station can only receive signals within a 65° angle before the signal is lost. A ranger team is located at point E while another team heads to point F to attempt to lure the bears to a more remote location. If the arc formed by ECF is 110°, can the ranger station communicate with both teams, or will they risk losing the signal? What description can be given to the line that connects the ranger station with either point E or point F and how d

Answer 1

To anyone who wants to know this this is what I got:
The rangers would not be able to communicate:
EDF=1/2(360-110)
EDF=1/2(250)
EDF=1/2(250-110)
(1/2)(140)=70
EDF=70
Anything outside of 65 degrees would mean they could not communicate, and because the angle is 70, they cannot communicate.
