Question

The world's tallest unsupported flagpole is believed to be a 282-ft-tall steel pole located in Surrey, British Columbia. During the course of a year, the longest shadow cast by the pole is 359 ft. long. Find the angle of depression formed.

Answer 1

As shown in the attached figure we have

`tan(\alpha )=(282)/(359)\\\\\therefore \alpha =tan^(-1)((282)/(359))\\\alpha =37.95^(o)`

Now we have
`\alpha =\lambda`

Thus angle of depression is
`37.95^(0)`
