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

[christinono]

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} :wink:

OP, do you know the sine and cosine rules?
