Step-by-step explanation:
Since an interior angle is 150 degrees, its adjacent exterior angle is 30 degrees. Exterior angles of any polygon always add up to 360 degrees. With the polygon being regular, we can just divide 360 by 30 to get 12 sides.
a reflexion across the x axis
vertical stretch by a factor of 2
a horizontal shift 3 units left
a vertical shift 4 units down
The answer here is simple these triangles are congruent your answer is 4.
