Most people apply the latter approach, which uses the tangents of the angles to the top and bottom and a true horizontal distance to the subject tree.

Vertical height of the tree is measured to the nearest foot. The most reliable tools for this purpose are an Abney hand level, a hypsometer, or a transit. Lacking those, you can use a straight stick.
