don't use that....if you have to use that find another side first

if so, how do i find the other side?

use pythagoras.....as i have stated above

ok, 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

i just explained the easiest method to find out any answer

see 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

asapbleh Group TitleBest ResponseYou've already chosen the best response.0
I dont seem to have another side

another side would be ^2=1^2+x^2 x^2=91=8 x=2sqrt2

Problem: 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 ?
