Answer 2

Given:

Distance away from the foot of an erect flag post = 5m

Angle of elevation = 50°

To find:

Height of the flag post.

Solution:

Let $h$ be the height of the flag post, $x$ be the distance away from the foot of the post. The problem is shown in figure as below:

Here, $x=5m$

From ΔABC,

tan 50° = $\frac{AB}{BC}$

$1.2=\frac{h}{5}$

On cross-multiplying,

$h=1.2*5=6m$

Height of the flag post is 6m.

Height of flag post is 6m.
