This must be a typo -- a building 24 cm high.

24 centimeters is about the length of my arm from my elbow to my hand.

A building 24 cm high???
Anyway, I will let you decide what units you are using.

Distance of tree from building ---- x
tan 60° = 24/x
x = 24/tan60° = ....

height of tree ---- h
tan 45° = (24-h)/x
1 = (24-h)/x
x = 24-h

solve for h
