12.5

OpenStudy (anonymous):

the side "x" is opposite of the 30°

OpenStudy (anonymous):

yes so that would be 25sin(30)

OpenStudy (anonymous):

sine = opposite / hypotenuse hypotenuse is 25 here, so sine = x / 25

OpenStudy (anonymous):

we don't know x, but we know sine because it's always the same value for 30° sine(30) = x / 25 (sine(30) is known) sine(30)*25 = x @jakejoker that means is completely right
