C.

Step-by-step explanation:

The answer is C, as as any value of m will make the equation true.

Such as if we used 2 as a substite value for m.

Lets simplify both equations:

Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.

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.
