Question

alguém???? por favor​

Answer 1

Explicação passo-a-passo:

sen 45° = 4/AB

0,71 = 4/AB

0,71AB = 4

AB = 4/0,71

AB = 5,66

tan 45° = 4/b

1 = 4/b

1b = 4

b = 4/1

(b = 4)> BC

sen 60° = 4/AC

0,87 = 4/AC

0,87AC = 4

AC = 4/0,87

AC = 4,62

tan 60° = 4/b

1,73 = 4/b

1,73b = 4

b = 4/1,73

(b = 2,31) > BC

AB + AC + BC =

5,66 + 4,62 + 4 + 2,31 = 16,59

5)

M = C . (1 + i)^t

M = 1500 . (1 + 0,02)^3

M = 1500 . (1,02)^3

M = 1500 . 1,061208

M = 1591,81
