.. Amy has
10 CDs in a CD holder. Amy's favourite group is Edex.
She has 6 Edex CDs in the CD holder. Amy takes one of these
CDs at random. She writes down whether or not it is an Edex CD.
She puts the CD back in the holder. Amy again takes one of
these CDs at random. Complete the probability tree diagram.

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.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

answer: b f g .
