Question

Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is. The
left-right (horizontal) direction is commonly called X-axis. The up-down (vertical) direction is
commonly called Y-axis. In the above Cartesian Coordinates graph, few points are marked for
reference.

(i) Find the distance between E and F.
(ii)Calculate the midpoint of A and B
OR
What is the midpoint of A and E?
(iii) What is the coordinate of D?
✓

Answer

i) 1.41 units
ii) (0,4.5) or (4,0.5)
iii) (-1,-2)

The great Stupa at Sanchi is one of the oldest stone structures in India, and an important Monument of Indian Architecture. It was originally commissioned by the emperor Ashoka in 3rd century BCE. Its nucleus was a simple hemispherical brick structure built over the relics of Buddha. It is a perfect example of combination of solid figures. A big hemispherical dome with a cuboidal structure mounted on it.

Read the following text carefully and answer the questions that follow:
Basant and Vinod lives in a housing society in Dwarka, New Delhi. There are two building in their housing society. The first building is 8 meter tall. One day, both of them were just trying to guess the height of the other multi-storeyed building. Vinod said that it might be a 45 degree angle from the bottom of our building to the top of multi-storeyed building so the height of the building and distance from our building to this multi-storeyed building will be same. Then, both of them decided to estimate it using some trigonometric tools. Let's assume that the first angles of depression of the top and bottom of an 8 m tall building from top of a multi-storeyed building are $30^{\circ}$ and $45^{\circ}$, respectively.
Image
i. Now help Vinod and Basant to find the height of the multi-storeyed building.
ii. Also, find he distance between two buildings.
