Find the distance of the following point from the origin :
(0 , 11)
उत्तर
P (0,0) , Q (0 , 11)
PQ = `sqrt (("x"_2 - "x"_1)^2 + ("y"_2 - "y"_1)^2)`
`= sqrt ((0 - 0)^2 + (11 - 0)^2)`
`= sqrt 121`
= 11 units

- Make a labelled figure on the basis of the given information and calculate the distance of the boat from the foot of the observation tower.
- After 10 minutes, the guard observed that the boat was approaching the tower and its distance from tower is reduced by 240(`sqrt(3)` - 1) m. He immediately raised the alarm. What was the new angle of depression of the boat from the top of the observation tower?
