Find the height of the tree from the given information.

Amman wants to measure the height of a tree on the other side of a river. He chooses a rock beside him on the river bank and lays out a base line 70 M long, perpendicular to the line of sight from the rock to the base of the tree. The angle of elevation from the rock to the top of tree is 80. At the other end of his base line, Amman measures the angle between his base line and the line of sight to the base of the tree to be 510. How tall is tree, correct to the nearest M?
