+180 Caitlin wants to calculate the height of a tree on the opposite bank of a river. To do this, she lays out a baseline of 100 m long and measures the angles along the baseline to be 80° and 27°. From the corner with the 80° angle, the angle of elevation to the top of the tree is 26°. Is this information sufficient to solve the problem? If so, determine the height, h, of the tree to the nearest tenth of a metre. If not, explain what would be needed to solve the problem.
