The correct answer is: translation, then reflection.
<u>Step-by-step explanation:</u>
In geometry, translation is described as the movement of an object or figure horizontally or vertically. While flipping an object or figure across a vertical or a horizontal line is called reflection.
From the attached picture, we can see that the figure can be shifted vertically from point P to R by some units.
And then if we reflect the figure NMP across the line which joins P & R we get the triangle STR.
Therefore, we need to first translate the triangle MNP and then reflect it to map onto TSR.
Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D
