प्रश्न
If the ratio of the height of a tower and the length of its shadow is `sqrt3:1`, what is the angle of elevation of the Sun?
उत्तर
Let C be the angle of elevation of sun is θ.
Given that: Height of tower is `sqrt3` meters and length of shadow is 1.
Here we have to find angle of elevation of sun.
In a triangle ABC,
`⇒ tanθ =(AB)/(BC)`
`⇒ tan θ=sqrt3/1` ` [∵ tan 60°=sqrt3]`
`⇒ tan θ=sqrt3`
`⇒ θ=60 °`
Hence the angle of elevation of sun is 60°.

Lakshaman Jhula is located 5 kilometers north-east of the city of Rishikesh in the Indian state of Uttarakhand. The bridge connects the villages of Tapovan to Jonk. Tapovan is in Tehri Garhwal district, on the west bank of the river, while Jonk is in Pauri Garhwal district, on the east bank. Lakshman Jhula is a pedestrian bridge also used by motorbikes. It is a landmark of Rishikesh. A group of Class X students visited Rishikesh in Uttarakhand on a trip. They observed from a point (P) on a river bridge that the angles of depression of opposite banks of the river are 60° and 30° respectively. The height of the bridge is about 18 meters from the river. |
