. If the tower is 100 m high, the distance of point P from the foot of the tower is: Question 6
The angle of elevation of the sun, when the length of the shadow of a tree 
times the height of the tree, is:
times the height of the tree, is: Question 7
A tree is cut partially and made to fall on ground. The tree however does not fall completely and is still attached to its cut part. The tree top touches the ground at a point 10m from foot of the tree making an angle of 30 °. What is the length of the tree?
Question 8
At a point on a horizontal line through the base of a monument the angle of elevation of the top of the monument is found to be such that its tangent is 
. On walking 138 meters towards the monument the secant of the angle of elevation is found to be 
. The height of the monument (in meter) is:
. On walking 138 meters towards the monument the secant of the angle of elevation is found to be . The height of the monument (in meter) is: Question 9
The angle of elevation of the top of a tower from a point A on the ground is 30 °. On moving a distance of 20 meters towards the foot of the tower to a point B, the angle of elevation increases to 60 °. The height of the tower is:
