hey guys,
I cannot for the life of me figure out how to answer this question. Help please? It will be muchly appreciated.

Oh, the answer was : yes the tree can hit the shed.
tree = 12 m
shortest distance to shed = 13xsin(65)= 11.78 m     <---- what even..

The shortest distance from the tree to the shed will be a straight perpendicular line from the shed to the tree    in my crude diagram.

This distance will therefore be    as the perpendicular line makes a right angle triangle with the points   and then it is just simple trigonometry.

As    the tree will hit the shed.
