D. x - 9y + 4 = x + 4 + (-9y)
Answer:
96 in 3
Step-by-step explanation:
Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.

Answer:
20.6 km
Step-by-step explanation:
Using (East, North) coordinates, the hiker's position ends up being ...
22.2(cos(-45°), sin(-45°)) +40.1(cos(65°), sin(65°))
We're only interested in the second coordinate of this total, which is ...
22.2sin(-45°) +40.1sin(65°) ≈ -15.698 +36.343 = 20.645 . . . km
The y-component of the hiker's position at the end of the second day is 20.6 km north of her starting location.
X and y vary directily means
y=kx
72=3k
divide both sides by 3
24=k
k=24
y=72
