3. A yield sign is an equilateral triangle
with sides 30 in. long. By arranging the
triangles as shown, the manufacturer
can use the sheet of aluminum to
make 10 yield signs. How much
aluminum is left over when yield
signs are made?

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

can you rephrase the question ? it is unclear : -)

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.
