tirar vs sacar
Tirar is throw/pull/bin. Sacar is take out/get/produce. Both get confused with each other and with other verbs.
tirar
Throw, pull, knock over, throw away, or waste — a surprisingly violent range of meanings.
Tira la basura.
Take the rubbish out / bin it.
Throw it away — tirar is the verb for binning things. Nothing to do with taking the bin outside (that's sacar).
Tira de la cuerda.
Pull the rope.
Tirar de = to pull. The opposite of empujar (push). Doors in Spain are often labelled tirar/empujar.
Tiró la taza al suelo.
He knocked the cup onto the floor.
Threw or knocked — tirar for things ending up on the floor, deliberately or not.
sacar
Take out, get something, produce, take a photo, or achieve a result.
Saca la basura.
Take the rubbish out (outside).
Take it out of the house to the bin. Compare: tirar la basura = throw it in the bin. Easy to mix up.
Saca una foto.
Take a photo.
Photos are always sacar — you extract the image. Never 'toma una foto' in Spain (though common in Latin America).
Sacó buenas notas.
She got good grades.
Sacar = to get/achieve results. Very common for exams, competitions, outcomes.
Tricky bit
'Tirar la basura' (throw the rubbish in the bin) vs 'sacar la basura' (take the rubbish bag outside). Same rubbish, same English phrase 'take out the rubbish' — two different Spanish verbs depending on the action. Learners use them interchangeably and get corrected.
