Question

The length of the shadow of a building is 90 meters, as shown below:
What is the height of the building?

Answer 1

Use tangent function.
tan 30 = h/90
hence h = 90tan30

Answer 2

let me grab a calculator

Answer 3

We have tanx=opposite side/adjacent side
here tan30=(ht.of building)/(length of shadow)
height of building=tan30*(length of shadow)
ie..=90*tan30

Answer 4

i got 51.96

Answer 5

correct
