Reflections. PLS HELP WILL MARK BRAINLIEST! if you dunno don't put anything. :) Point Q is reflected over the x-axis onto its image Q'(-7,-3). Determine the coordinates of the pre-image.

(7, 3)
(-7, 3)
(7, -3)
(-7, -3)

(-7,3)

Step-by-step explanation: plz

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

i think the length is 12 and the width is 17
