Question

Sally is tracking a submarine on a sea floor using a sonar detector, as shown below.



What is the depth, in meters, at which the submarine is located?





490 tan 28˚

490 sin 28˚

Answer 1

490 over cos of 28
490 over sin 28

Answer 2

this is the picture

Answer 3

\[490/\sin 28\]

Answer 4

How did you slove for this?

Answer 5

well sin 28= the hypotenuse/the depth. This is fundamental trigonometry. the hypotenuse of the triangle is given as 490, so depth=490/sin 28.

Answer 6

oh ohkay i get it thankyou :D
