Question

In a building, there is a window situated at mid-point of height of the building If there is a point in the ground whose distance is root3/2 times
the height of the building, then the angle of elevation of the window from the same point​

Answer 1

Step-by-step explanation:

Let the window be Q.

Height of the building be AB

Let the point P at a distance of xm.

In ΔQPB

tan30

0

=

BP

QB

=

x

10

x=

tan30

0

10

=10

3

In ΔABP

tan60

0

=

x

h

h=xtan60

0

h=x

3

h=10

3 × 3

=30m

So, the height of building = 30 m
