Help! Not good with Trig and Geometry! Will mark brainliest!!
Amanda and Jeremiah are standing on the same side of a large lake. They are separated by a horizontal distance of 4000 ft. Both Amanda and Jeremiah can see a helicopter that is directly above the horizontal distance between them. Amanda’s angle of elevation to see the helicopter is 60° and Jeremiah’s angle of elevation to see it is 30°. What is the distance between Jeremiah and the helicopter?

Respuesta :

We have a right angled triangle here so we can use trigonometry. Let the distance between Amanda and the helicopter be x , then:-

cos 60  = x / 4000
x = 4000 *  cos 60 
  = 4000 * 1/2
  = 2000 feet Answer
