Best ResponseYou've already chosen the best response.1don't use that....if you have to use that find another side first

Best ResponseYou've already chosen the best response.0if so, how do i find the other side?

Best ResponseYou've already chosen the best response.0ok, then if i need to find csc theta, if cot theta = 21/20 and sin theta>0 then would my answer be \[\sqrt{1+21/20}\] or

Best ResponseYou've already chosen the best response.1see you have sin theta= 1/3 now 1 is perpendicular and 3 is hypotenuse now use pythagoras theorem to find another side and since you have three sides you can find any of the trigonometric value

Best ResponseYou've already chosen the best response.0Problem: Find csc theta if cot theta=21/20 and sin theta>0 if i use the pythagoreas, then would it be 20^2+x^2=21^2 ?

Best ResponseYou've already chosen the best response.0omg, so ive been doing it wrong? ive been using \[\csc \theta=\sqrt{1\cot ^2\theta}\]
