You can find the adjacent side of angle A using the Pythagorean Theorem (or if you know your Pythagorean triples this is just a 3,4,5 with all the sides multiplied by 2). to get the adjacent side = 8
Then you can find the trig functions.
sin A = 6/10 = 3/5
cos A = 8/10 = 4/5
tan A = 6/8 =3/4
csc A = 5/3
sec A = 5/4
cot A = 4/3
