trigonometry ratio

Explanation:

cotangent is reffer to as the inverse of tangent
i.e tan B = opp/ Adj then
cot B = #1/"Adj" = "Adj"/"opp"#
#therefore cot theta = 3/2 = "adj"/"opp"#

#adj = 3 and opp = 2#

you can draw the triangle from there
then find the third side using pythagoras theorem
since the third side =# hyp = x#
therefore
#hyp^2 = opp^2 + Adj^2 #

therefore #x^2 = 2^2 + 3^2

#x^2 = 4 + 9#

#x^2 = 13#
#x =sqrt13#
