Hitung lh nilai sin A, cos A, dan tg A, pada Δ abc siku siku di c, jika diketahui panjang sisi sisi: A. A=8 cm dan B= 6 cm A. A=5 cm dan B=7 cm

a = 8 cm , b = 6 cm , maka c = 10 cm
sin A = a/c = 8/10 = 4/5
cos A = b/c = 6/10 = 3/5
tg A = a/b = 8/6 = 4/3

a = 5 cm , b = 7 cm , maka c = √(5²+7²) = √74
sin A = a/c = 5/√74 = (5/74)√74
cos A = b/c = 7/√74 = (7/74)√74
tg A = a/b = 5/7
