sin(x) = opposite/hypotenuse cos(x) = adjacent/hypotenuse tan(x) = opposite/adjacent which one do you use

theyadoreshayyy:

tangent ?

snowflake0531:

... what are the sides 12 and 13

theyadoreshayyy:

sine ?

snowflake0531:

no

snowflake0531:

don't guess.... 13 is obviously hypotenuse, and 12 is adjacent, so we use cosine

snowflake0531:

cos(x) = 12/13 So solve for x

theyadoreshayyy:

4.07 ?
