Question

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?

Answer 1

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:

`x=8\cos (205)`
`y=8\cdot\sin (205)`
