Answer:
1. Sine ratio of angle ∠C = 12/13
2. cos ratio for ∠C = 6/10
Step-by-step explanation:
1. sin = perpendicular /hypotuse
=> 12/13
2. cos = base / hypotuse
=> 6/10

( Part A: Ok 2,6 and 6,2 and 0,3 and 4.5,6 you can add 2,6 and every other number with part b which is 2,6 +0,3= 2,3 and also 2,6+4.5,6= 6.5,12 and you can do the same with 6,2 and you will get 6,5 and 10.5,8)
(Part B: 2,3^6.5,12^6,5^10.5,8)
~Riley Hope this helped :P
The regular period is 2pi. If you look up or type in a graphing calculator you can see that's when the sine function starts to repeat itself.
