I hope this helps you
tanA= height /base= -3/1
3^2+1^2=hypothenus ^2
hypothenus =squeare root of 10
sinA=height /hypothenus
sinA=3.square root of 10/10
The answer would be c because you cannot add unlike variables so the real answer should be 2j+2k, but b/c it's not an answer choice the answer is c)
