I am COMPLETELY stumped with this question. Can someone help me get started on a couple of steps? Hints? Thank you so much.
Streelights A, B, C, D, and E are placed 50 m apart on the main road. The light from a streetlight is effective up to a distance of 60m.
a. Determine the distance from A to the farthest point on the side road that is effectively illuminated.
b. Determine the length of the side road that is effectively illuminated by both streetlights C and D.
