A surveyor sights the top of a building with a handheld range finder. The top of the building is 148 feet and 2 inches away. The angle of elevation is 56 degrees. Find the distance from the surveyor to the building.

I already found the answer to this problem ( 82ft and 10in) but it has a second part,

PartII: The angle of depression to the bottom of the building is 4 degrees. Find the height of the surveyor.

I found the answer to this too (5ft 10in)

I just need help with this final part:
PartIII: Find the height of the building
