The cable car

The cable car has a length of 3,5 kilometers and an angle of climb of 30 degrees. What is the altitude difference between Upper and Lower Station?

Result

y =  1750 m

Solution:

$c = 3.5 \ km = 3.5 \cdot \ 1000 \ m = 3500 \ m \ \\ A = 30 \ ^\circ \ \\ \ \\ \sin A = y / c \ \\ \ \\ A_{ 1 } = (A \rightarrow rad) = (A \cdot \ \dfrac{ \pi }{ 180 } \ ) = 0.523598775598 \ \\ \ \\ y = c \cdot \ \sin(A_{ 1 }) = 3500 \cdot \ \sin(0.5236) = 1750 = 1750 \ \text { m }$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
