Question

The angle of elevation of the top of a tower from a point 30 m away from its foot is a
30°. Then, the angle of elevation of the top of the same tower from a point 10 m away from its foot is_________.​

Answer 1

Answer:

60

Step-by-step explanation:

BD is30m

BC is 10m

tan30=AB/BD

1/√3=AB/30

AB=10√3

now

for other angle of elevation

AB/BC=10√3/10

=√3

but √3 is value of tan60

the angle of elevation is60
