3. symbolize the following arguments and show that they are formally valid with a deduction. make sure that you fully specify the symbolization key. (a) most pandas live in china. all who live in china speak chinese. therefore, many pandas speak chinese. (b) all pandas eat bamboo. nothing that eats bamboo is a fan of poutine or tourtiere. every quebecer is a fan of poutine or tourtiere. so, no pandas are quebecers. (c) only po the kung fu panda could defeat jean-claude van damme in a fight. chuck norris is a martial artist, but he is not po the kung fu panda. therefore, some martial artists can't defeat jean-claude van damme. (here, treat .po the kung fu panda' as a proper name.)

step-by-step explanation:

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.
