same idea as last time, but now use cos(angle) = adjacent/hypotenuse

SohCahToa Right? Have you heard that?
SOH, CAH, TOA is a handy way to remember the trig ratios It's pronounced as "soak, a, toe-a" (that's how I remember it anyway) For SOH S = sine O = opposite H = hypotenuse which means sine(angle) = opposite/hypotenuse For CAH C = cosine A = adjacent H = hypotenuse which means cosine(angle) = adjacent/hypotenuse For TOA T = tangent O = opposite A = adjacent which means tangent(angle) = opposite/adjacent
lol you read my mind that was about to be my next question :) thanks! okay so would CAH be 3/5?
yes 6/10 = 3/5
Okay yay :P thanks!!
you're welcome
