I am not sure if this is a GRE question. And please follow the rules of posting question.
The first triangle and the second triangle are similar. Both of them are right triangle and both the triangles have one angle equal to \(x\) degrees.
We can say that:
In triangle 1 we have hypotenuse=\(\sqrt{3^2 + 4^2}=5\) .
height of triangle 1/ height of triangle 2 = hypotenuse of triangle 1/ hypotenuse of triangle 2.
\(\frac{10}{4}=\frac{m}{5}\) so \(m=12.5\).
Hence option B is greater.
Please type out your questions and also share the source of the questions.

Correct: B
In the left triangle, as it is a right side one, the other side is 5. And we have: cos x = 4/5
In the right triangle, angle x is equal to angle x in the left triangle. We have cos x = 10 / m = 4/5, so m is 12.5
And B is bigger than m
