Question

A car travels straight for 20 miles on a road that is 30° north of east. What is the east component of the car’s displacement to the nearest tenth of a mile?

Answer 1

17.3 miles.

So basically when u draw u realise u have the hypotenuse as 20 and an angle of 30 degrees. to get the horizontal component u simply take cos30 =x/20

so x = 20*cos30 which is 17.3 miles.

hope this helps
