Some of the important "given" information is outside of the photo.
We need to know that the two triangles are similar.
And we need to know that the WHAT ? of angle M is 9/40.
I believe the answer is cubic centimeter
The line x = -5 is a vertical line, therefore the line perpendicular to this line is the horizontal line of the form y = a.
We know that it passes through the point (1, π) → x = 1, y = π.
Therefore we have answer: A) y = π.
3SQRT(3). It is equal to the short side time Square Root of 3.
