The horizontal distance between the two buildings is l = 32.6 meters.

It can be obtained from geometric relations.

DC=L*tanβ-L*tanα

=L*tan43 24' -L*tan35 12 '

=30.83-23.00

=7.83

About 7.8 meters

Height of high-rise building H=L*tanβ.

=32.6*tan43 24 '

About 30.8 meters

So the two buildings are 30.8 meters and 7.8 meters high respectively.
