Question

If cos=3/5 then tan=____.

What is trying to be done. Am I supposed to find the equivalent of cos=3/5 to tan or what?

Please explain thank you.

Answer 1

Drawing triangle helps. We know that \(\cos\theta=\dfrac{Adj}{Hyp}=\dfrac{3}{5}\), so we can say that adj is 3 and hyp is 5.



And we know that \(\tan\theta = \dfrac{Opp}{Adj}\)

We need to find Opp. Use pythagorean theorem to find Opp.

Answer 2

4^2 + 3^2 = 5^2 = 16 + 9 = 25

Answer 3

Right, so what is Opp?

Answer 4

Opposite is 4 so 4/3 then is the answer?

Answer 5

yes
