Question

an observer 1.5m tall is 28.5m away from a chimney from her eyes is 45°. What is the height of the chimney​

Answer 1

Answer:

30m

Step-by-step explanation:

In Triangle ABE,

tan45=Opp / Adj = AB / 28.5

tan45 = AB / 28.5

1 = AB / 28.5

AB = 28.5m

 AC = AB + BC

=28.5 + 1.5

=30m

Height of the chimney =30m

Answer 2

Answer:

Step-by-step explanation:

1. height of boy = 1.5m
2. distance = 28.5m
3. height of chimney = ?

tan 45° = perpendicular/base

so,   1 = p/28.5

        p = 28.5

         p = 28.5 + boy height

               p = 28.5 + 1.5

p = 30m
