What is the value of $$Sin(X)$$ if Opp = 27 and Hyp = 45?

$$Sin(X) = \frac{27}{45} = \frac{3}{5}$$

What is the relationship between Sine, Cosine, and Tangent?

$$Tan(X) = \frac{Sin(X)}{Cos(X)}$$

If $$Sin(X) = \frac{4}{5}$$ , what is $$Cos(X)$$ ?

$$Cos(X) = \sqrt{1 - Sin^2(X)} = \sqrt{1 - \left(\frac{4}{5}\right)^2} = \frac{3}{5}$$
