# Transformation matrix in affine matrices

I'm studying this for my computer graphics course under the topic of affine transformations but I've searched everywhere and I don't get how to do this

Given the transformation matrix:

$$M = \begin{pmatrix} 3.4641016 & \!\!\!\!\!\!\!\!\!\!\!\!\!-1 & 2\ \\ 2 & \!\!\!\!\!\!\!\! 1.7320508 & 5 \ \\ 0 & \!\!\!\!\!\!\!\!\!\!\!\!\! 0 & 1\ \end{pmatrix}$$

1. Show that this matrix has a rotation transform and find the rotation angle. (2 points)
2. Show that this matrix has a scale transform and find the scaling components in $$x$$ and $$y$$ directions. (2 points)
3. Show that this matrix has a translation transform. Find the translation components in $$x$$ and $$y$$ directions. (2 points)
