What is the height of the building? Solution: - Let the height of the building be \( h \). - The distance from the person to the building's base is 50 meters. - Using tangent: \(\tan \theta = \frac{h}{d}\) \[ h = d \times \tan 30^\circ = 50 \times \frac{\sqrt{3}}{3} \approx 50 \times 0.577 = 28.85 \text{ meters} \] Add the person's eye level if necessary to get total building height.
