This isn’t homework related but what methods do you guys recommend for shifting realities ? .I’ve tried the raven method for wee
elena55 [62]

Answer:

subs

Explanation:

I've seen subliminals online that are supposed to help shifting. You could see for yourself if they work for you. You could probably also use the method where you act like you already have your desires and results. I have seen a lot of people act as if they have their desires and affirm it constantly. Ex: you want to lose weight, so you act as if you already are your desired weight and tell yourself that you are such and such weight, and don't contradict it by saying that you aren't. I hope that this helps.

You went 100 miles north and 14
skad [1K]

Answer:

82 degrees

Explanation:

consider your staying point to be the center of a circle. this center has the coordinates (0, 0).

the radius of the circle is the distance you walked East (14 miles).

I assume your teacher means as "angle of displacement" the angle between the East-West line going through your starting point and the direct line from your starting point to your current position.

then the 100 miles North is tan(displacement angle)×14.

as it is the same, if you first went North and then East, or the other way around. you end up at the same point, with the same coordinates.

so, again.

100 = 14×tan(angle)

tan(angle) = 100/14 = 50/7 = 7.142857...

the displacement angle is then 82 degrees.
