Find $$\sin(X)$$ if the opposite side is 27 and the hypotenuse is 45.

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

If the adjacent side is 8 and the hypotenuse is 10, what is $$\cos(D)$$ ?

$$\cos(D) = \frac{8}{10} = \frac{4}{5}$$ .

If the opposite side is 36 and the adjacent side is 48, find $$\tan(X)$$ .

$$\tan(X) = \frac{36}{48} = \frac{3}{4}$$ .

What is the Pythagorean identity involving sine and cosine?

$$\sin^2(X) + \cos^2(X) = 1$$ .

What is the ratio for cosecant?

The ratio for cosecant is $$\frac{hypotenuse}{opposite}$$ .

What is the ratio for secant?

The ratio for secant is $$\frac{hypotenuse}{adjacent}$$ .

What is the ratio for cotangent?

The ratio for cotangent is $$\frac{adjacent}{opposite}$$ .

If the hypotenuse is 10 and the opposite side is 6, find $$\sin(X)$$ .

$$\sin(X) = \frac{6}{10} = \frac{3}{5}$$ .
