L1890et +a+ = height of D. I. in feet
Let +b+ = height of K. in feet
---------------------------------------
(1) +a+=+b+-+2119+
(2) +b+=+2a+%2B+229+
-------------------------------
Substitute (2) into (1)
(1) +a+=+2a+%2B+229+-2119+
(1) +-a+=+-1890+
(1) +a+=+1890+
and
(2) +b+=+2%2A1890+%2B+229+
(2) +b+=+3780+%2B+229+
(2) +b+=+4009+
4,009 feet
