Una moneda de bronce tiene una perforación cuadrada en el centro, la cual tiene un área de 16 mm2. Si la moneda se encuentra inicialmente a 5 °c y se coloca por unos minutos en agua hirviendo (100°c), ¿cuál será ahora el área del orificio?

x = -2

y = 848

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.
