3x+6=57
3x=57-6
3x=51
x=51/3
x=17
apply the formular.

27.1739% percent. to find that, all you have to do is multiply 2.5x100. that equals 250. divide this by 9.2, and that is your answer
Since the triangles are similar, they will have proportional sides. With this knowledge, we can make the proportion
to solve for x.
Firstly, cross multiply: 
Next, divide by 10 on both sides, and your answer will be 4 = x, or the first option.
