Tiana and Rachel each have a record collection. • The number of records in Tiana’s collection can be represented by x. • The number of records in Rachel’s collection is 4 times the number of records in Tiana’s collection.
• The total number of records in both collections is 160.

What is x, the number of records in Tiana’s collection?

answer: no, but if it does it's a obvious pattern.

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.

the radius is 2 times the diameter.
