i think this makes more sense if you draw a diagram
so basically, as we are working out the horizontal component, decide if you need to use sin or cos.
as the side is next to the angle, you would use cosine.
thus, your answer would be 27cos49
(the vertical component would be 27sin49)
hope this helps :)
