Answer:
Me, I just learned it, I can help
Step-by-step explanation:
Formula:
ax^2 + bx + c
The tangent of the angle gives the ratio of the height of the lighthouse to the boat's distance
.. tan(angle of depression) = (lighthouse height)/(boat distance)
Then the distance to the boat is
.. boat distance = (lighthouse height)/tan(angle of depression)
We want to find the difference between two distances, so
.. boat travel = (lighthouse height)*(1/tan(first angle) -1/(tan(second angle))
.. = (200 ft)*(1/tan(17°31') -1/tan(46°41'))
.. ≈ 445.10 ft

Answer:
Step-by-step explanation:
92÷2= 46
188÷ 1/4=752
276÷ 1/6= 1656
So the third one is the answer
Answer:
n=11
Step-by-step explanation:
Solve for n by simplifying both sides of the equation, then isolating the variable.
