Aiden estimates that the length of a piece of rope is 7.2 inches. If it's actual length is 6.5 inches, what is the percent error of Aiden's estimate?

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.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

83-45=38

38 was the other number

hope your goes well, here's a turkey
