What are the correct trigonometric ratios that could be
used to determine the length of LN? Check all that apply.
-
N
sin(20°) = LN
70°
cos(70°) = 8
tan(70°) = LN
sin(20°) = 8
cos(70°) = LN

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
