Step-by-step explanation:
The vertices of the given triangle are the points:
(2, -1), (4, -5), and (5, -3).
To rotate the figure 90 degrees clockwise, we will use the following rule
(x, y) -----> (y, -x)
So, each vertex becomes
(2, -1) ----> (-1, -2)
(4, -5) ---> (-5, -4)
(5, -3) ---> (-3, -5)
Therefore, using the points (-1, -2), (-5, -4), and (-3, -5) we get that the triangle after the clockwise rotation is:
