They said was the best ive had a question up sense the day before yesterday and havent even had a person see it.
the balance of michelle's average balance checking account at the beginning of last cycle was $500, and the only transaction for the cycle was a check that michelle wrote for $200, which cleared exactly half­-way through the cycle. on what amount did michelle's checking account pay interest last cycle?

okay wait before i answer, is this for your points on a graph?

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.
