Step-by-step explanation:
Firstly ,
mark point A at the top of red building
draw a line parallel to ground from point A connecting it to point B
the distance between A and b will be 15 m
( first side)( AB)
i.e. 36-28 = 8 ( second side) ( BC)
Now.
you can easily find it with Pythagoras theorem
AC² = AB² + BC²
AC² = (15)² + (8)²
AC² = 225 + 64
AC² = 289
AC = √289
AC = √ 17 × 17
AC = 17
Thus the distance between their tops is 17 m
