An airplane starts from a station and rises at an angle of 10 deg with the horizontal. By how many feet will it clear a vertical wall 100 ft. High and 900 ft from the station?

I don't get it. Can you provide an image that represent the situation in the problem. Thanks.

Thanks!

My solution

$\tan10^{\circ}=\frac{100'+h}{900'}$h = 58.69 ft.
