25°
65°
67°

Calantha · Answer

The measure of the  angle of depression  from the helicopter to the girl’s line of sight is  67 degrees.       What is a right angle triangle?  A  right angle triangle  has one of its angle as 90 degrees. The sides and angles can be found using trigonometric ratios.  Therefore,  angle of depression  from the helicopter can be found as follows:   tan x = opposite / adjacent   where  x = angle of depression  Hence,  tan x = 660 / 280  tan x = 2.35714285714  x = tan⁻¹ 2.35714285714  x = 67.1231281953   x = 67°   Therefore, the measure of the  angle of depression  from the helicopter to the girl’s line of sight is 67 degrees.    learn more on  right triangle  here: https://brainly.com/question/26253402  #SPJ1
