As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.
In order to solve for x we can set up the proportion between the horizontal and vertical sides:

Solving this proportion for x implies 
Now you can solve for m and p using the pythagorean theorem, because both triangles are right:

Then, we know that the hypothenuse of the big triangle is m+p, so we have

which implies

Answer:
the second one iy s very incorrect
Answer:

tep-by-step explanation:
In order to find the integral:

we can do the following substitution:
Let's call

Then

which allows us to do convert the original integral into a much simpler one of easy solution:

Therefore, our integral written in terms of "x" would be:

It would be B, the second triangle.
