pls my test is tomorrow and its 11:30pm lol:(. so the question, a person at the top of a 25 yard tall hill looks down at a tree that is 100 yards diagonally away from the person. what is the angle of depression from the person to the tree

Respuesta :

Answer:

76°

Step-by-step explanation:

Taking the cosine ratio of the angle of depression :

  • cos θ = height of hill / distance from person diagonally
  • cos θ = 25/100
  • cos θ = 1/4
  • θ = cos⁻¹ (0.25)
  • θ = 76° (nearest whole degree)
