Question

4- neste triângulo, calcule a,c e h.​

Answer 1

Resposta:

Olá !

h² = 12² + 7,2²

h² = 144 + 51,84

h² = 103,68

h = 10,18

h = √(m * n)

10,18 = √(7,2)*(a-7,2)

10,18² = 7,2a - 51,84

7,2a = 103,63 + 51,84

7,2a = 155,47

a = 155,47/7,2

a = 21,60

21,60² = 12² + c²

c² = 466,56 - 144

c² = 322,56

c = 17,96
