Check all that apply. if csc theta = 13/12 then:
a. tan theta = 12/5
b. sin theta = 12/13
c. cos theta = 12/13
d. sec theta = 12/13

Cosec t(heta) = 13/12
1/sin t = 13/12
sin t = 12/13
cos t = √ (1 - (12/13)² ) = √ ( 1 - 144/169 ) = √25/169
cos t = 5/13
tan t = sin t/ cos t = (12/13) / (5/13) = 12/5
sec t = 1 / cos t = 13/5
A ) and B )  are correct:
tan theta = 12/5 and sin theta = 12/13
