Answer:
3tanA = 4
tan A = 4/3
perpendicular = 4kunits
base = 3k units
hypotenuse = 5k units
therefore sin^2 A = (4k/5k)^2 = 16/25
cos^2A = (3k/5k)^2 = 9/25
That's the answer:)

bro, why can't the perpendicular be 8 units and base be 6 units then, the hypotenuse will be 10 units, still Tan A = 4/3 only,. Your answer isn't accurate,.
oK
I got it..
just add it now bro
Clear,..
