The horizontal distance between light house and boat is 1588.78 feet approximately.
The figure is given by,
Here, AB = height of the lighthouse bacon light above the water = 139 feet
Now angle ACB = 5 degree
Let the horizontal distance of light house from the boat = BC = x feet
So by trigonometric function we get,
tan 5 = AB/BC
tan 5 = 139/x
x = 139/tan 5 = 1588.78 (approximately)
Hence the horizontal distance between light house and boat is 1588.78 feet approximately.

No of substes is given by 2^n where n is the no of elements.
Here, n = 3
Therefore, number of subsets = 2^3 = 8
Answer:
2/1and6/3 because if you do cross multilication they both equal 6
Step-by-step explanation:
I am 100% sure it is A. I did the test and it showed it was A.
Please leave a thanks.
160 $ = 100%
x $ = 70%
100 x = 11200
x = 112
160,00 - 112,00 = 48,00$
