Answer:
7
Step-by-step explanation:
If A is 7 units away from the x-axis then the x-axis is seven units away from A.
That's if I read the question right.

Answer:
- red boat distance: 42 miles
- angle at lighthouse: 22°
Step-by-step explanation:
The Law of Cosines can be used to find the distance from the red boat to the lighthouse.
b² = l² +r² -2lr·cos(B)
b² = 18² +30² +2·18·30·cos(120°) = 1764
b = √1764 = 42
The distance from the red boat to the lighthouse is 42 miles.
__
The angle at the lighthouse can be found using the law of sines.
sin(L)/l = sin(B)/b
L = arcsin(l/b·sin(B)) = arcsin(18/42·sin(120°)) ≈ 21.79°
The angle between the boats measured at the lighthouse is about 22°.
When x=3, y=9 and when x=6, y=3 bc u plug them into the equation
Answer:
z = 23 degrees.
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees. Therefore:
62 + 95 + z = 180
z = 180 - 95 - 62
z = 180 - 157
x = 23 degrees (answer).
