Describe a similarity transformation that maps triangle abc to the triangle rst

a(3,-2) b(0,4), c(-1,-3) and r(-4, -6), s(8,0) t(-6,2)

my answer was rotation 270 degrees counterclockwise followed by a translation 4 units right, then a dilation centered at (8,0), k = 2
can someone pls tell me if this is right also?

9.4.34  question   to estimate the height of a stone  figure, an observer holds a small square up to her eyes and walks backward from the figure. she stops when the bottom of the figure aligns with the bottom edge of the  square, and when the top of the figure aligns with the top edge of the square. her eye level is 1.811.81 m from the ground. she is 3.703.70 m from the figure. what is the height of the figure to the nearest hundredth of a  meter?

In the figure, triangle aob and triangle boc form a linear pair ,find the measure of x
