The length of the shadow of a pole inclined at `10^@` to the vertical towards the sun is 2.05 metres, when theelevation of the sun is `38^@`. Then, find the length of the pole.

A

`(2.05 sin 42^@)/(sin 38^@)`

B

`(2.05 sin 42^@)/(cos 42^@)`

C

`(2.05 sin 38^@)/(sin 42^@)`

D

`(2.05 sin 42^@)/(sin 38^@)`

To solve the problem, we will follow these steps: ### Step 1: Understand the Geometry We have a pole inclined at an angle of \(10^\circ\) to the vertical. This means that the angle between the pole and the ground is \(90^\circ - 10^\circ = 80^\circ\). The elevation of the sun is \(38^\circ\), and the length of the shadow is \(2.05\) meters. ### Step 2: Draw a Diagram Let's label the points: - Let point A be the top of the pole. ...
