Assuming C=90 A=50 b/c all angls of a traingle are equal to 180 degrees so 90+40=130. 180-130=50

I don't know about b and c though

Well.....I'm assuming a is a leg.... we have....with the Law of Sines

6/ sin 50 = b/ sin 40 [ note if B = 40, A must = 50]

b = 6sin40 / sin50 = about 5.035

And the hypotenuse = c = sqrt [6^2 + 5.035^2] = about 7.833
