You guys are right. There's no answer

#

I'll take the 0

#

I can't do this shit

small sand
#

first u make the scale

#

like 10mph = 1 cm

#

so if the speed is 190mph then ur lenght of the line would be 19 cm

#

so make that line w bearing of 120°

#

it's a

#

see u draw the 19cm line and 1.5 cm line

#

then use the parallelogram law

#

the purple line which i have drawn is the resultant vector

#

measure the length of the purple line

#

and using the scale 10 mgh = 1 cm

#

u can find the speed

thorn hill
#

I got the speed for this

#

It's 197.92

small sand
#

so what u need?

thorn hill
#

I'm looking for the direction

#

Nothing I've tried works

small sand
#

which angle are u finding?

#

@thorn hill ?

thorn hill
#

tan^-1(164.54/110)

#

Idk if I'm supposed to add or subtract 90

small sand
thorn hill
#

I'll try

small sand
#

ok

thorn hill
#

I'm looking for the direction of the resultant

small sand
#

Ok

#

can u tell me what speed did u get?

thorn hill
#

197.92

small sand
#

I'm getting 3.8 degrees in anticloxkwise direction

#

Clockwise*

thorn hill
#

That's not correct

small sand
#

wait a min lemme recheck

#

@thorn hill

thorn hill
#

I already tried that too

#

It didn't work

small sand
#

Try 123. 76

#

@thorn hill

thorn hill
#

ok

#

One of them is right

#

How'd you get it?

small sand
#

yes

#

see they have asked the bearing right

thorn hill
#

yes

small sand
#

so we have to take in the angle from n to the resultant vector

small sand
#

So that angle w have to calculate

#

So I had used the sin rule to calculate the small angle which I got was 3.76

#

then i had added 120 to it

thorn hill
#

Ok

Thank You hype
