For x, it would be
y = 2x - 5
+5 +5
y + 5 = 2x
2 2 2
y/2 + 5/2 = x
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: ∠ABD =
∠C
<u>Step-by-step explanation:</u>

Answer:
126
Step-by-step explanation:
angle ZWY = 180 - 90 - 63 = 27
Base on the given information, the length of XW is same with the length of ZW, which means they have the same angle.
Quadrangle has angle of 360
360(quadrangle) - 27(ZWY)- 27(XWY) - 90(WZY) - 90(WXY)
= 126
Answer:
- amplitude: 3
- period: π
- axis: y = 0
- range: [-3, +3]
Step-by-step explanation:
The amplitude is the multiplier of the sine function: 3.
The period is 2π divided by the coefficient of x: 2π/2 = π.
The equation of the axis is any added constant: y = 0.
The range is the axis value ± the amplitude value: from -3 to +3.
