- Homework Statement
- The base of a mountain starts at elevation of 900 metres above sea level and the top is at 15000 metres. The table below gives the angle of elevation of a path with respect to horizontal at different locations along a section of the route. The distances are measured along the path, starting from elevation of 1000 metres above sea level.

Find the lower and upper limit of angle of elevation at the end of the section

- Relevant Equations
- Riemann Sum

Integration

distance (metres) | Angle of elevation (degree) |

950 | 7 |

1500 | 12 |

1800 | 15 |

3300 | 20 |

I think I don't need to use information about 900 metres because the path starts from elevation of 1000 metres. I imagine the distance will be the hypotenuse of a triangle and the height of a certain location will be the "opposite" part of a right-angled triangle (the height is the side in front of angle of elevation)

But somehow I feel that the information given by the question is not enough to determine the lower and upper limit of angle of elevation at the end of the section (I think the question asks about the angle of elevation at point on top of the mountain)

Is it correct that the information is not enough? Or am I missing something?

Thanks
