Answer:
√'xy/y
Step-by-step explanation:
1. [x*y^(1/2)] / [y * x^(1/2)]
= [x^(1/2) * y^(1/2)] / y
= (xy)^(1/2) / y
You'll get your answer as : √'xy/y

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
