A car travells 20 km due north and then on a bearing of 90 degrees for 12km. Use a scale drawing.
Bearing clockwise from N? That is East.
BU A CAR
To create a scale drawing of the car's journey, follow these steps:
1. Start by drawing a line segment to represent the initial 20 km journey due north. Label one end of the line as the starting point (e.g., A) and the other end as the final point (e.g., B).
2. Next, draw a line perpendicular to segment AB from point B. This line represents the car's change in direction at a bearing of 90 degrees.
3. Measure and mark a distance of 12 km along the line drawn in step 2. Label this point as C.
4. Connect points B and C to form a right-angled triangle with BC as the hypotenuse.
5. Using a ruler or a scale, measure and determine the appropriate scale for the drawing. For example, if you decide to use a scale of 1 cm:5 km, then every 1 centimeter on your drawing will represent 5 km on the actual map.
6. Finally, use your chosen scale to measure and draw the accurate distances for segments AB and BC on the scale drawing.
By following these steps, you can create a scale drawing that represents the car's journey of 20 km due north and then a bearing of 90 degrees for 12 km.
