All right, so here we have two bicyclists who are starting out from the same point and they're making their way to the same campground through two different routes.
00:11
Where they begin is a and the campground is located at point b.
00:15
The first cyclist heads east for 1080 meters and then turns due north for 1430 meters and arrives at the campground.
00:24
The second cyclist instead heads north first for 1950 meters then turns to face directly towards the campgrounds direction and goes that way until he hits the campground.
00:37
How far away is the bicyclist from the campground when he makes his turn and at what angle due east should he be bicycling in order to reach the campground? so let's take advantage of the information we do have.
00:50
The first cyclist went 1080 to the right and then 1430 up.
00:55
That means that the cyclist here who went 1950 up overshot the campground by 520 feet or rather meters.
01:04
So this distance right here is 520 because you know the campground is right here and we can draw a straight line across to make a triangle.
01:12
Now the bottom side of this triangle should be 1080 because the second biker has not deviated from east or west just north.
01:20
So he's still 1080 meters away from the campground...
