1 How will you describe the position of a table lamp
on your study table to another person?​

Answer 1

Answer:

For describing the position of table lamp on the study table, we take two lines, a perpendicular and a horizontal line. Considering the table as a plane(x and y axis) and taking perpendicular line as Y axis and horizontal as X axis respectively. Take one corner of table as origin where both X and Y axes intersect each other. Now, the length of table is Y axis and breadth is X axis. From The origin, join the line to the table lamp and mark a point. The distances of the point from both X and Y axes should be calculated and then should be written in terms of coordinates.

The distance of the point from X- axis and Y- axis is x and y respectively, so the table lamp will be in (x, y) coordinate.

Here, (x, y) = (15, 25)

This is your answer

Answer 2

Answer:

To describe the position of a table lamp on the study table, we have two take two lines, a perpendicular and horizontal. 

Considering the table as a plane and taking the perpendicular line as Y axis and horizontal as X axis. 

Take one corner of the table as origin where both X and Yaxes intersect each other. 

Now, the length of the table is Y axis and breadth is Xaxis. 

From the origin, join the line to the lamp and mark a point. 

Calculate the distance of this point from both X and Y axes and then write it in terms of coordinates.

Let the distance of a point from X axis is x and from Y axis is y then the position of the table lamp in terms of coordinates is (x,y).
