Answer 2

A: Burj Khalifa
B:Burj Al Arab
\[\theta = 2.675^{0}\]
d= 10.85 km
\[\tan \theta = PQ/d\]
where PQ is the length of burj khalifa intercepted in the triangle containing \[\theta\].
so
\[PQ = d Tan \theta\]
for the complete length of burj khalifa, the height of Burj Al Arab is also to be known....
