Panjang sisi miring segitiga siku-siku yang memiliki luas 30cm^ dan tinggi 6cm adalah... Tolong Jelaskan!! ;)
RahmaAliya
L = 30 cm² L = 1/2 a . t 30 = a . 6 : 2 a = 30/3 a = 10 cm
sisi miring = √t² + a² sisi miring = √6² + 10² sisi miring = √36 + 100 sisi miring = √136 sisi miring = 11,66 cm

Diket : Luas = 30 cm Tinggi = 6 cm Ditanya : panjang sisi miring Jwb : L = 1/2 a x t 30 = 1/2 x a x 6 30 = 1/2 x 6a 30 = 3a 10 = a Sisi miring = c alas = a tinggi = t c kuadrat = a kuadrat + t kuadrat c kuadrat = 10 kuadrat + 6 kuadrat c kuadrat = 100 + 36 c kuadrat = 136 c = akar dri 136
L = 1/2 a . t
30 = a . 6 : 2
a = 30/3
a = 10 cm
sisi miring = √t² + a²
sisi miring = √6² + 10²
sisi miring = √36 + 100
sisi miring = √136
sisi miring = 11,66 cm
Luas = 30 cm
Tinggi = 6 cm
Ditanya : panjang sisi miring
Jwb :
L = 1/2 a x t
30 = 1/2 x a x 6
30 = 1/2 x 6a
30 = 3a
10 = a
Sisi miring = c
alas = a
tinggi = t
c kuadrat = a kuadrat + t kuadrat
c kuadrat = 10 kuadrat + 6 kuadrat
c kuadrat = 100 + 36
c kuadrat = 136
c = akar dri 136
