Difference 6469

The cable car rose at an angle of 15 °. The height difference between the upper and lower stations is 106m. Calculate the path's length.

Correct answer:

x =  410 m

Step-by-step explanation:

$$\begin{gathered} \alpha =15°\to \text{rad}=15°\cdot \frac{\pi }{180}=15°\cdot \frac{3.1415926}{180}=0.2618=\pi /12 \\ h=106\text{m} \\ \sin \alpha =h:x \\ x=h/\sin \alpha =106/\sin 0.2618=410\text{m} \end{gathered}$$
