    find the third side by pythagoras, you get \(\sqrt{3^2-2^2}=\sqrt{5}\) then use "adjacent over opposite"

    you need to find the missing side in the right triangle using pythagoras' theorem |dw:1358483748710:dw| once you have found x then find \[\tan( \theta)\] lastly talke the reciprocal to find \[\cot(\theta)\]
