Mathematical Modeling in Science and Engineering>Using Trigonometric Ratios to Calculate Distances and Angles in Fields(TEKS.M.9-12.6.D) Practice Test

A student stands 120 m from the base of a wind turbine on level ground. The angle of elevation to the hub is 28°. Construct a right-triangle trig model and find the approximate hub height h.

A technician in West Texas stands 90 m from the base of a wind turbine on level ground and measures an angle of elevation of $35^\circ$ to the top. Let $h$ be the turbine height. Which equation best models this situation?
