The bearing of A from B is 219.If B is equidistant from A and C and the perimeter of triangle ABC is 15m, find

1) The bearing of C from A
2) The distance between A and C

C can lie anywhere on a circle with center at B and radius AB

All we know that that the triangle is isosceles, and since AB = BC,
AB + AB + AC = 15

The bearing of A really has no relevance. I suspect you have left something out.
