Answer: OPTION C.
Step-by-step explanation:
Observe the triangle ABC attached.
Notice that the angle of depression is represented with 
.
Knowing that the top of a lighthouse is 260 feet above water and the ship is 270 feet offshore, you can find the value of by using arctangent:
In this case you can identify that:
Therefore, substuting values into , you get that the angle of depression is:
Here is how to solve this:
18 +4 = 22 bulls
45 + 4 = 50 cows
The original ratio was, 18:45 but now its 22:50 so, no the ratio will not be the same.

The answer would be 13 1/2 because you turn the 12 into a fraction then change the division sign into a multiplication sign and find the reciprocal of 8/9 which is 9/8 you could now divide 12/1 divided by 9/8 you could cross simply then dove to get 27/2 and in the end you get 13 1/2 if you turn the improper fraction into a mixed number.
We simply need to solve for the circumference of the imaginary circle.
Given:
Diameter = 25 feet.
Circumference = 2 * radius * π OR Circumference = diameter * π
C = 25feet * 3.14
C = 78.50 feet
The pony will walk 78.50 feet to complete one trip around the circle.
