A long pole is broken in a storm. Top end of the broken pole touched the head of a man at a distance of 'd'. Then find the angle between the man and the pole that before storm.

A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground by making 30^(@) angle with the ground. The distance between the foot of the tree and the top of the tree on the ground is 6m. Find the height of the tree before falling down.

A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground by making 30^@ angle with the ground. The distance between the foot of the tree and the top of the tree on the ground is 6 m. Find the height of the tree before falling down.

A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground by making 30^(@) angle with the ground. The distance between the top of the tree and the ground is 10m. Find the height of the tree.

The force between two magnet poles separated by a distance 'd' in air is 'F'. At what distance between them does the force become doubled ?

Two poles of heights 23m and 30m stand on the plane ground. If the distance between their feet is 24m, find the distance between their tops.

A tree is breaken without separating from the stem by the wind. The top touches the ground making an angle 30^(@) at a distance of 12m from the foot of the tree. Find the height of the tree before breaking.

A steel pole is 10 m high. To keep the pole upright one end of a steel wire is tied to the top of the pole while the other end has been fixed on the ground. If the steel wire makes an angle of 45 with the horizontal through the base point of the pole, find the lenght of the steel wire is

Let 10 vertical poles standing at equal distances on a straight line, substend the same angle of elevation alpha at a point O on this line and all the poles are on the same side of O. If the height of the longest pole is 'h' and the distance of he foot of the smallest pole from O is 'a', then the distance between two consecutive poles is

A body is projected at an angle of 45^(@) from a point on the ground at a distance of 30 m from the foot of a vertical pole of height 20m. The body just crosses the top of the pole and strikes the ground at a distance s from the foot of the pole on the other side of the pole. Then, s
