HIDDEN TREASURE A.crew is using radar tosearch for pirate treasure hidden under water.Suppose the boat is facing due east, and the radargives the polar coordinates of the treasure as(8, 205°). What are the rectangular coordinates forthe hidden treasure?

Respuesta :

EXPLANATION

The rectangular coordinates are given by the following expression:

x=r*cos(θ) y = r*sin(θ)

Where r is the radius = 8 and θ is the angle = 205 degrees

Replacing terms give us the rectangular coordinates as shown as follows:

[tex]x=8\cos (205)[/tex][tex]y=8\cdot\sin (205)[/tex]
