Height of building is  76 feet.

Step-by-step explanation:

In the figure below,

AB is the building , DE is the tree standing in half way between the state and building.

Let angle at C be

In ΔABC,

tan =

tan =              ......(1)

In ΔDEC,

tan =

tan =                 ......(2)

Comparing (1) and (2) ,

  =  

⇒

Thus, Height of building is  76 feet.

the answer is 13

step-by-step explanation:

5*5=25
