tan A = perpendicular/base =4/5

so hypotenuse =√(16 +25)

sina = 4/√(16+25)

cosa = 3/√(16+25)

sina×cosa = 12/41

Hey Mate...❤
Here's Ur Answer....❤

tanA = opp. side/adj.side = 4/5
so, (hypotenuse) = root (41)
sinA = opp. side/hyp = 4/root(41)
cosA = adj. side /hyp = 5/root(41)
therefore, sinA × cosA = 820

HOPE IT HELPS...❤
