Trig

The Leaning Tower of Pisa is 55m tall. The tope edge of the tower is 5m out from the bottom edge.
What is the angle created between the ground and the tower?
Round your answer to the nearest degree.

tan -1 (55/5) = 85 degrees

but my Brother says I did it wrong that the angle is
tan -1 (5/55) = 5 degrees

I say the angle that we are supposed to figure is the one that would be between the building and the ground opposite the 90 degree angle that has a length of 55m. He says that the angle is the angle between the 55 side length and the top of the building. I say he is wrong he has figured the vertical distance of 5 degrees.

And that my 85 degrees is correct because is says between the ground and the tower.
