A tower subtends angle x° at a point A at its base plane. If the angle of depression of the foot of the tower at a point B at b height above A is y°, then the height of the tower is
ans : B tan x° cot y°
DIAGRAM SHALL B ENUF.....
ek aur......
A pole stands vertically inside a triangular park ABC. If the angle of elevation of the top of the pole from each corner of the park is same, then inABC, the foot of the pole is at the :
circumcentr
orthocent
centroid
incenter
ans circum
1oh k... thnk u once again... no sorry thnx 5th time again LOL.....
1ha ha....
By the way n speed with which u solve them its gonna b a futile battle to count da tot no of thnx... LOL......
Sir pl. most essentially reply to my scrap wenever u hav time... i'll wait.....
Coz u r the one who has gone thru this grill n hav cum out trumps!!!!
62The second part is very simple
The height is H
the angle is A
then The distance of the foot of the pole from each vertex is given by
H cot A for all the 3 vertices
which is equal.
SO it gives you the circumcenter :)
1hmmm.... yah..... y didnt it strike me then!!!!
k neways now i got it.... hope i'll not 4get these things on the D'DAY
