IF YOU DO THIS ILL GIVE YOU A ANSWER A, B, C are four towns B is 30 kilometres due east of A C is 20 kilometres due north of A D is 45 kilometres due south of A work out the bearing of B from C

Take point A as (0,0)

That would mean that B is (0,30) because it is 30 kilometers east

C would be (30,0) because it is 30 kilometers north

D would be (-45,0) becuse it is 45 kilometers south

The distance from B (0,30) to C(30,0) is 42.43 kilometers using the distance formula

The distance from D (-45,0) to B (0,30) is 54.08 kilometers using the distance formula

they are simplified
