Un terreno de forma triangular tiene 250 pies de base por 180 pies de altura cual es la magnitud de su area en metros cuadrados

Depotion can i think

Is this a question of an answer

It is the areas with lines. this may sound a little confusing, but i hope it !

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
