| Description: | This activity will show students a real-life problem that uses trigonometry to solve for an unknown. The USA TODAY Snapshot "When a ruler isn't enough" explains how a tree hunter uses a clinometer and trigonometry to determine the height of a tree. The student will be asked to determine the angle that would be recorded on the clinometer when they measure the two included sides of the triangle. Students will use inverse trigonometric functions to determine this angle. The following Math TODAY resources are available as a PDF download: The activity is designed for use with the TI-83 Plus and TI-83 Plus Silver Edition, TI-84, TI-84 Plus. |
