Answer: 
Step-by-step explanation:
First you need know some general formuals of factorization such as
so you have 
And,
so you have 
If you use them, then you can modify your equations such as

That formed a right triangle with legs 4 and 3.
The distance point X moved to point X', d, is the hypotenuse of the right triangle.

The correct answer is B.
Determine and recall first the trigonometric functions:
Sin A = Opposite/Hypotenuse
Cos A = Adjacent/Hypotenuse
Tangent = Opposite/Adjacent
If for example we try to take an angle, for example the Y, then Y is opposite Y. The Hypotenuse will be the longer side which is going to denoted by X and the next side will be Adjacent which will be denoted by Z.
Use this test to answer:
Sin Y = Y/X
where:
Y = opposite
X = hypotenuse
Cos (90 - y) = cos (90 - 50) = cos 40
where Z = 40
we look for cos Z = Y/X
Therefore,
Sin Y = Cos (90 - Y)
The best choice would be neither

The ratio at which Courtney took pictures is 10:2 which can be simplified to 5:1.
The ratio at which Marry took pictures is 20:3 which is already in its most simplified form
