tan A = perpendicular/base =4/5
so hypotenuse =√(16 +25)
sina = 4/√(16+25)
cosa = 3/√(16+25)
sina×cosa = 12/41
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
