Answer:
Why is it dangerous to listen to an MP3 player at excessively loud volumes for extensive periods? The mp3 player can be played above 85 decibels, which would cause damage to the hearing receptors, leading to (permanent)hearing loss.
Answer:
sin a=-4/5
we have sina=perpendicularp/hypotenuseh=-4/5
let p=-4k
h=5k
by Pythagoras theorem
h²=p²+b²
(5k)²=(-4k)²+b²
25k²-16k²=b²
(3k)²=b²
b=√(3k)²=3k
now
cos a =b/h=3k/5k=3/5
