I don't understand how using the drawing helps determine the sin of 30 degrees though, or how to explain that in words

sin30 = o/h

whats opposite side and hypotenuse in that triangle
anonymous
  • anonymous
opposide is sqrt 3, hypotenuse is 2. so sin30 = sqrt 3 / 2

opposite* lol

  • dan815
nope
dan815
  • dan815
sqrt3 is the adjesecent side to 30

opposite is the side the angle doesnt touch

opposite is 2?

so to explain that in words, i'd say that you use a 30-60-90 triangle, divide the opposite by the hypotenuse and that's the sine?

memorize SOHCAHTOA

sin = opposite x hypotenuse, cos = adjacent x hypotenuse, and tan = opposite x adjacent. yes i learned it. just got confused for a second.
