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

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

jasonxxBest ResponseYou've already chosen the best response.1
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

im sorry, this is another problem, not the above triangle

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

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 ?

square both sides. multiply through by sin^2 solve for tan
