Aircraft altitude calculation

Radar sees an aircraft at an altitude angle of 15°24', and the direct distance from the radar is 5545 m. At what altitude does the aircraft fly?

Final Answer:

h =  1472.51 m

Step-by-step explanation:

$$\begin{gathered} \alpha =15°24^{\prime }=15°+\frac{24}{60}°=15.4°=15.4 \\ c=5545\text{m} \\ \sin \alpha =h:c \\ h=c\cdot \sin \alpha =c\cdot \sin 15.4°=5545\cdot \sin 15.4°=5545\cdot 0.265556=1472.51=1472.51\text{m} \end{gathered}$$
