Answer 2

Answer:

1

Step-by-step explanation:

$\tan(23) \tan(35) \tan(67) \tan(55) \\ on \: rearranging \\ \tan(23) \tan(67) \tan(35) \tan(55) \\ by \: complimentary \: angles \\ \tan(23) \cot(90 - 67) \tan(35) \cot(90 - 55) \\ \tan(23) \cot(23) \tan(35) \cot(35) \\ as \: w \: know \: that \: cot = \frac{1}{ \tan} \\ hence \: \\ all \: values \: gets \: cut \\ answer = 1$
