A winery has a vat with two pipes leading to it. The inlet pipe can fill the vat in 7 hours, while the outlet pipe can empty it in 10 hours. How long will it take to fill the
vat if both pipes are left open?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

i think the answer is fried chicken ; >

step-by-step explanation:

dude thats to long figure it

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.
