the scale of a map says that 6 cm represents 15 km. what distance on the map represents an actual distance of 6 kilometers

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

The least common denominator of 4/8 and 11/18

Me because i don't understand how to do it.: )
