Which is the more precise measurement? 18 inches 18.55 inches 17.5 inches 19.775 inches

option D

Step-by-step explanation:

the correct answer is option D

A precise measurement is one in which we can measure the smallest of the value.

In 17.775 we can measure the smallest value of 0.001

In 18.55 we can measure smallest value  up to 0.01

In 17.5 we can measure smallest value  up to 0.1

In 18  we can measure smallest value of 1.

hence, the correct answer will be option D which will be 17.775 in which we can measure 0.001 value.

da freeck kinda math is this just drop out

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.
