Question

How far apart are the two yellow bulidings?also,what is the height of the taller yellow buliding?fast please full explanation​

Answer 1

Answer:

total height is 30 m

distance is 17.32

Step-by-step explanation:

by trigonometric identity

here we can see in pic that there is 2 triangle ️

ABC and CED

for tallest building let's total height is (20+X)m

so

base B will

tan60=(20+X)/b

for the remaining parts EC which assumed X

tan30= p/b =X/b......2

(b is same as it is the distance between the 2 building )

by 1 and 2

(20+X)/tan60=X/tan30

(20+X)/X=tan60/tan30

=)20+X=3X

and 2X=20

X=10m

so

total height is 20+10=30m

b=17.32

so

20+X=X
