Ahotel plans to use marble for part of the floor lobby. the marble section of the floor will be in the shape of a triangle with a base of 80 feet and a height of 60 feet. the marble flooring costs $6 per square foot. how much will the marble for the floor cost?

i think asking google will you get the answer to that question

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.
