See the attached diagram.

height of window, AC or n = 15m
height of building = AB = (n+m) = ?
distance between the buildings = x

In triangle AOW,
tan 45 = (15/x)
⇒ 1 = 15/x
⇒ x = 15m

In triangle WCB
tan 30 = m/x
⇒ 1/√3 = m/15
⇒ m = 15/√3 = 5√3 = 8.66m

Height of building = m+n = 15+8.66 = 23.66 m
