A river runs west to east. A tree stands on the edge of one bank of the river and a man standing directly opposite on the other bank of the river wishes to determine the width of the river and the height of the tree. If the man walks 7m west along the bank, the angle of elevation to the top of the tree is 17 degrees. If he walks 5 m east from the point opposite the tree, the angle of elevation to the top of the tree would be 19 degrees. Draw the diagram and determine the height of the tree and the width of the river.
