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
True. It determines our
ability to handle a strenuous workout or not. This is why it is important to
take a check-up from a doctor before beginning any kind of exercise
activity. This is to ensure that you
have a safe workout and that you can the amount of exercise in that program.
