part a: on your own paper, create a back-to-back stemplot. submit a list of the stems you used in order from least to greatest. justify your reasoning for split or nonsplit stems. (4 points)
part b: compare and contrast the two data sets. justify your answer using key features of the data (center, shape, and spread). (6 points) (10 points)

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.
