In the image created, we can see that we can apply sin ∅ = opposite / hypotenuse. the opposite side is the distance between 2 parallel bars and the ∅ is the angle made by the diagonal on top.
Given:
∅ = 60°
Opposite = 9 ft
Hypotenuse = 9 / sin 60 = 10.39 ft
the length of the support AB is 10.39 ft

Answer:
the height of the taller building is 14.47 m
Step-by-step explanation:
Given the data in the question as illustrated in the image below.
form the image; ( Triangle BDE )
we know that sin∅ i= opposite/hypotenuse
so; sin12° = BE / 21.5
BE = 21.5sin12°
BE = 4.47 m
since, EA = DC = 10 m
BA = BE + EA
BA = 4.47 m + 10 m
BA = 14.47 m
Therefore, the height of the taller building is 14.47 m
It is different because partial products is you part the number to get the answer.They are the same because both strategies give you the same answer. Hope it helps
