Answer:
P= cos ( a ) = 40 /41
Step-by-step explanation:
your question as translated is as
If sin α = 9/41, the value of P = cos α
As sin (a) = cos (90-a)
also sin (a) = opposite / hypotenuse
and also
Adjacent = [tex]\sqrt{hypotenuse^{2} /opposite^{2} }[/tex]
[tex]\sqrt{41^{2} -9^{2} }[/tex] =40
adjacent = 40
we know Cos (a) = adj/hyp
so cos(a) = 40/41 which is equal to also P.
