Two poles of height 12 m. and 4 m. are situated in such a way that the sun rays through the top of a pole also passes through the top of other. What is the distance between the poles?
It is given that the sun rays make an angle of 45 degree with the horizon
A 45 degree angle means for every meter height there must be one meter distance.
The height difference between the two poles is 8 meter, so they must be 8 meters apart.
A body is projected at velocity of 40 m/s, after 2 sec it crosses a vertical pole of height 20.4 m. What is angle of projection and horizontal range?
At a particular time the shadow of a men of 170 cm height is 204 cm on the ground and at the same time and on the same ground the shadow of a pole is 600 cm. Find the height of the pole?
Two ships are sailing in the sea on the two sides of a lighthouse. The angle of elevation of the top of the lighthouse is observed from the ships are 60° and 30° respectively. If the lighthouse is 144 m high, what is the distance between the two ships?
If a bamboo 32 meters high is broken by wind so that the tip meets the ground at a point 16 meters far from the base, at what height above the ground was it broken?
From a point A on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point A from the foot of the tower is:
