step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

just pick what you think i need more time let me know if this

step-by-step explanation:

really your just stupid if you don't know this

step-by-step explanation:

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
