Consider A to be at (0,0)
B lies on the circle with center at (0,0) and radius 190
The ship ended up at a point P on a circle with center at (0,0) and radius 270, such that BP = 180
If we let B be due north of A, then the bearing of P from B is z degrees, where
cosz = 80/180
Now you can find the angle θ that the ship is off via
tanθ = 180sinz/270 = 2/3 sinz
In kyoto, put the 'to' at the end of the beginning of the word and then it's fine. I never noticed that!
Answer:
b
Step-by-step explanation:
Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
Hope this helps!
