Let
 h------------> height of window 

we know that

tan 51°=h/6-------> h=6*tan 51°-------> h=7.4 m

the answer is 
h=7.4 m

Answer:

Option B. 7.4 m.

Step-by-step explanation:

Angle of depression given = 51°

Distance of the fountain from the building = 6 m

We have to find the height of the window from the ground.

Now tan 51° = height of window/ distance of building from the fountain.

1.23 = height of window/6

height of window = 6×1.23 = 7.40 m.

Option B. is the answer.
