Answer:

  • We are given two observations
  • Lets use geometric properties to solve
  • 300 meters is the hyp or c
  • Theta is 25 degree
  • Theta changes to 60 degree
  • Hence tan(25)= x1/300
  • x1=139.8
  • Now let's find the second height
  • tan(60) =x2/300
  • x2=519.6 ft
  • Now x2-x1
  • So the difference is 379.8 ft
