Answer:
A clinometer is a relatively simple tool that is used to determine the slope angle. The height of tall objects can be determined using trigonometry concepts based on the angles measured. A big protractor can simply be converted into a clinometer.
A clinometer can also be be used to measure tree heights, pole heights, tower heights, and building heights, as well as slopes for preliminary surveying, grade work, and site drainage. Vertical angles can also be assessed for cellular and satellite installation, as well as other applications.
