A car travelled 7km40degree west of north and then 10km east.what is the resultant displacement using scale drawing

To find the resultant displacement of the car, we can use a scale drawing. Here's how you can do it:

1. Start by drawing a horizontal line to represent the east-west direction and a vertical line to represent the north-south direction. Label the starting point of the car as "O".

2. From the starting point "O", draw a line at a 40-degree angle west of north. Since the car traveled 7 km in this direction, make the line 7 units long.

3. From the end point of the first line, draw another line horizontally to the east. This line should be 10 units long to represent the 10 km traveled east.

4. Now, connect the starting point "O" with the end point of the second line. This line represents the resultant displacement of the car.

5. Measure the length of this line using a ruler. Let's say it measures "x" units.

6. Determine the scale of your drawing. For example, if you use a scale of 1 cm represents 1 km, and the measured length of the line is 5 cm, then the resultant displacement is 5 km.

So, to determine the resultant displacement of the car using a scale drawing, you will need to accurately measure the length of the resultant vector and apply the appropriate scale.
