Hello. lax600!

Are you sure you understand bearings?

They are measured clockwise from due North.

Try it with this diagram . . .Radar stations and are on an east-west line, 3.7 km apart.

Station detects a plane at with a bearing of 61°.

Station also detects the plane with a bearing of 331°.

Find the distance from to .Code:C * P * * Q : * * : : * * : : * *29°: : * * : :61°* * : : * 29° 61° *: A * - - - - - - - - - - - * B 3.7

We are given: .

. . Hence: .

We see that: .

. . Hence: .

Then: .

. . is a right triangle.

We have: .

Therefore: . km.
