Question

If cos A=3/5then the value of tanA?????

Answer 1

Answer:

See answer in above picture

Answer 2

Answer:

CosA=3/5

Here,Cos A =B/H

we have,

B=3 and H=5

Now,

by pythagoras theorem,

25=9+P^2

25-9=p^2

16=p^2

p=4

since,perpendicular or altitude is 4

Therefore,

TanA=p/b

TanA=4/3Ans.....
