Question

if forward bearing is 155 degree then back ward degree is what?

Answer 1

Plz elaborate the question something is missing

Answer 2

Actual bearing would be
When your bearing is less than 180°, add 200° and then subtract 20°
When your bearing is greater than 180°, subtract 200° and then add 20°
And in this case bearing is less than 180 so the backward bearing will be(155°+200-20)I.e (355-20) .....answer would be 335°.
