Question

If sin A =3/5 .find cos A and tan A
​

Answer 1

Answer:

cos 36.9=0.8

tan 36.9=0.751

Step-by-step explanation:

A=36.9

cos 36.9=0.8

tan 36.9=0.751

Mark me as brainliest

Answer 2

we know that,

sin A =p/h=3/5

from pithagoras theoram,

hypotenuse square=perpendicular square+base square so that,

we write it as

Base square=hypotenuse square-perpendicul square

base square= 5square-3square

25-9

16

so that base = 4

from tan titha=p/b

3/4

and from cos thitha =b/h

4/5...ans.
