sinA  = 24/25

Therefore opposite side is 24 and hypotenuse is 25.

a) To find length of third side

From the Pythagoren therom

(24)^2+(adjacentside)^2 = (25)^2

576+(adjacent side)^2 = 625

adjacent side = sqrt(625-576)

adjacent side = sqrt(49)

adjacent side = 7

b) ratio of cosA = adjacent side/hypotenuse

cosA = 7/25

c) ratio of TanA = opposite side/adjacent side

TanA = 24/7
