How are 0.6 and 0.60 equivalent

Because 0.6 and 0.60 are the same number just that the second one has an extra zero without that it will be 0.6

Step-by-step explanation:

they're the same because you can just take the 0 off because zero is nothing so u can just take it off

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.
