Answer:
240
Explanation:
We know that Y is 800m from X, and located 400m north of X.
That means the cosine of the bearing of Y from X is 400m/800m = 1/2
We should remember (or use a calculator with arccos) that the angle for which the cosine is 1/2 is 60deg.
The bearing of Y from X is 060.
To get the bearing of X from Y, we just need to add or subtract 180 and we arrive at the answer - 240

Answer:
They are formed when a river creates a meander.
Explanation:
It forms due to the river's eroding bank. After a long period of time, the meander becomes very curved, and eventually the neck of the meander becomes narrower and the river cuts through the neck during a flood, cutting off the meander which then creates an oxbow lake.
It is because you drink a lot of water. So the less water you drink the more yellow it is. It means you have healthy urine.
Answer:
0.70 d
Explanation:
m1 = 97 kg
m2 = 548 kg
m = 69.7 kg
Let the distance between m1 and m2 is d .
Let m be placed at a distance s from m2 so that the net force on m is zero.
Force between m1 and m is balanced by force between m and m2
G m1 x m / (d - s)^2 = G m x m2 / s^2
m1 / (d - s )^2 = m2 / s^2
97 / (d - s)^2 = 548 / s^2
(d - s)^2 / s^2 = 97 / 548
(d - s) / s = 0.42
d - s = 0.42 s
d = 1.42 s
s = 0.70 d
