A vertical pole fixed to the ground is divided in the ratio 1:9 by a mark on it with lower part shorter than the upper part. If the two parts subtend equal angles at a place on the ground, 25 m away from the base of the pole, what is the height of the pole?

A flagstaff on the top of the tower 80 meter high, subtends an angle tan ^(-1)(1/9right) at a.point on the ground 100 -meters away from the foot of the tower. Find the height of the flag-staff (in metres)

AB is a vertical pole with B at the ground level and A at the top . A man finds that the angle of elevation of the point A from a certain point C on the ground is 60^@ . He moves away from the pole along the line BC to a point D such that CD = 7 m . from D the angle of elevation of the point A is 45 then the height of the pole is

5 m high pole stands on a building of height 25 m. The pole and the building subtend equal angles at an antenna placed at a height of 30 m. The distanceo f the antenna from the top of the pole is

A pole 5 m high is fixed on the top of a tower. The angle of elevation of the top of the pole observed from a point 'A' on the ground is 60^(@) and the angle of depression to the point 'A' from the top of the tower is 45^(@) . Find the height of the tower. (sqrt(3)=1.732)

A tower of height b subtends an angle at a point 0 on the ground level through the foot of the tower and at a distance a from the foot of the tower. A pole mounted on the top of the tower also subtends an equal angle at 0. The height of the pole is

Two poles of heights 6 m and 11 stand vertically on a plane ground. If the distance between their feet is 12 m, what is the distance between their tops ?

The upper 3/4 th portion of a vertical pole subtends an angle theta such that tan theta=3/5 at a point in the horizontal plane through its foot and at a distance 40m from the foot. Find the possible height of the vertical pole.

An electrician wants to repair an electric connection on a pole of height 9 m. He needs to reach 1.8 m below the top of the pole to do repair work. What should be the length of the ladder which he should use, when he climbs it at an angle of 60^(@) with the ground? What will be the distance between foot of the ladder and foot of the pole?
