Let sin⁻¹(
) = x
Therefore, sin(x) =
x should lie in first quadrant because √3 and 2 both are positive.
Therefore, sin(x) = 60° = π/3
To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse
That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse
tan(25) = 89/x
x = 89/tan(25)
x = 190.86
after rounding, the answer is D, 191 feet
Greater than.
yards are a larger unit of measurement, so to convert it there are more millimeters to count the same amount of space.
