Do you know SOHCAHTOA?

um...kinda how do u know which one you use? sorry I am in special ed I am super slow in understanding even the simple stuff

$$sin\theta = \frac{opposite}{adjacent}$$
$$cos\theta = \frac{adjacent}{hypotenuse}$$
$$tan\theta = \frac{opposite}{adjacent}$$

Use the one which contains the unknown variable and the variable you are given.

$$sin\theta = \frac{opposite}{adjacent}$$

Actually, it's:

$$sin\theta = \frac{opposite}{hypotenuse}$$

OP, do you know the sine and cosine rules?
