A highway makes an angle of 6 with the horizontal.This angle is maintained for a horizontal distance of 5 miles.To the nearest hundredth of a mile, how high does the highway rise in this 5- mile section?Show the steps you use to find the distance.
Draw a diagram
tan 6° = d/5
d = 0.53 mi
A forest ranger spots a fire from a 28-foot tower. The angle of depression from the tower to the fire is 11 .
