Question

Ques-1 if sin0 =3/5
find the value of cos0 =?

pls solve fast.....​

Answer 1

Given: sin theta=3/5

Sin theta= opposite side/hypotenuse

3k/5k=opposite side/hypotenuse

==> Opposite side=3k

Hypotenuse=5k

Using Pythagoras theorem we get that adjacent side=4k.

Cos theta= adjacent side/hypotenuse

=4k/5k

=4/5

Hope it helps.. :)

Answer 2

Given: sin theta=3/5

Sin theta= opposite side/hypotenuse

3k/5k=opposite side/hypotenuse

==> Opposite side=3k

Hypotenuse=5k

Using Pythagoras theorem we get that adjacent side=4k.

Cos theta= adjacent side/hypotenuse

=4k/5k

=4/5
