Two planes left an airport at the same time and in still air. one flew east at 450 mi/h, and the other flew at 380 mi/h. in what direction did the second pilot fly if the two planes were 800 mi apart after 1 hour?

Step-by-step explanation:

we know that

Applying the law of cosines

where

c is the distance between the two planes after 1 hour

a is the distance of the plane 1 after 1 hour from the airport

b is the distance of the plane 2 after 1 hour from the airport

C is the angle between the direction plane 1 and the direction plane 2

step 1

Find the distance a

Multiply the speed by the time

step 2

Find the distance b

Multiply the speed by the time

step 3

Find the measure of angle C

we have

-----> given problem

solve for angle C

substitute the values

The direction plane 2 is equal to

see the attached figure to better understand the problem

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )
