two buildings are 60 feet apart across a street. A person on top of the shorter building finds the angle of elevation of the roo

inessss [21]

Answer:

The height of the taller building is $64\ ft$

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

$tan(20\°)=\frac{h1}{60}$

$h1=60*tan(20\°)$

step 2

Find the value of h2

with the angle of depression

we know that

$tan(35\°)=\frac{h2}{60}$

$h2=60*tan(35\°)$

step 3

Find the height of the taller building

The height of the taller building is the sum of h1 plus h2

$60*tan(20\°)+60*tan(35\°)=60*(tan(20\°)+tan(35\°))=64\ ft$
