Step-by-step explanation:
tan(theta) = 2
this means that opposite divided by adjacent is equal to 2.
this can occur if opposite = 2 and adjacent = 1
this would make hypotenuse equal to sqrt(2^2 + 1^2) = sqrt(5).
your other functions would then be:
sin (theta) = opp/hyp = 2/sqrt(5) = 2*sqrt(5)/5
cos(theta) = adj/hyp = 1/sqrt(5) = sqrt(5)/5
tan(theta) = opp/adj = 2/1 = 2
cot(theta) = adj/opp = 1/2
sec(theta) = hyp/adj = sqrt(5)/1 = sqrt(5)
csc(theta) = hyp/opp = sqrt(5)/2
