To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
It should be this answer i got it off the internet it should be right
Answer:
The height of the taller building is 
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the value of h1
with the angle of elevation
we know that


step 2
Find the value of h2
with the angle of depression
we know that


step 3
Find the height of the taller building
The height of the taller building is the sum of h1 plus h2
so
