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

Answer:
a. fly = 5.7
b. fly = 7.5
Step-by-step explanation:
a.
hoist/fly = 1 / 1.9
The new hoist is 3. To get this you have to multiply 1 by 3. That means you have to multiply 1.9 by 3 too.
1.9 * 3 = 5.7
b.
hoist/fly = 3/5 (this is the new ratio)
4.5 / 3 = 1.5
5 * 1.5 = 7.5
Answer:
The answer would be a=2.
Step-by-step explanation:
Since both sides of the equation are being multiplied by b then you would divide both of them by B. This will just remove the B from the equation entirely and leave you with a=2. I hope that this was helpful.
