when the probe reaches the ocean for approximately how far would the pro be from the team ships on the surface when measured horizontally round the nearest meter

when the probe reaches the ocean for approximately how far would the pro be from the team ships on the surface when measured horizontally round the nearest mete class=

Respuesta :

Given the angle of depression = 76.4

And the length from the probe to the ship = 3,900 meters

The horizontal distance between the probe and the ship = x

So, x represents the adjacent side to the angle 76.4

The hypotenuse = 3900 m

So,

[tex]\begin{gathered} \cos 76.4=\frac{adjacent}{hypotenuse} \\ \\ \cos 76.4=\frac{x}{3900} \\ \\ x=3900\cdot\cos \text{76}.4=917.054 \end{gathered}[/tex]

rounding to the nearest meter

so, the answer is option 1). 917 meters
