Question

If 5sinA=3 show that cosA /tan A=16/15

Answer 1

Answer:

Yes it is correct

Step-by-step explanation:

5sinA=3 so sinA=3/5

and we know that sintheta = p/h

then we find value of p=3 and h= 5

so by using pythogorous theorom find b= 4

then use value of p,h,b in cosA and tanA you get 16/15

Answer 2

Step-by-step explanation:

5sinA=3

sinA=3 /5

cosA /tan A=cosA/(sinA/cosA)

= (cosA)^2/sinA

=(1-(sinA)^2)/sinA

=(1-(3/5)^2) / (3/5)

=(1-(9/25)) *5/3

=((25-9)/25)*5/3

=16/15
