Answer:
sin = 9/15 -> 3/5
cos = 12/15-> 4/5
tan =9/12 ->3/4
csc=15/9 -> 5/3
sec =15/12 -> 5/4
cot = 12/9 -> 4/3
Other things :
SOH CAH TOA CHO SHA CAO
Sin = opposite/hypotenuse
cos= adjacent/hypotenuse
tan = opposite/adjacent
csc=hypotenuse/opposite
sec=hypotenuse/adjacent
cot=adjacent/opposite
opposite = 9
adjacent = 12
hypotenuse = 15
