Answer 1

A)

8 Horas

B)

Sim

C)

500 + 100 + 100 + 200 + 300 = 1200

1200---------- 500 (meios pelos extremos)

360 ----------- x

1200x = 180000

x = 180000/1200 = 150°

1200----------100

360------------x

1200x = 36000

x = 36000/1200 = 30°

1200----------100

360------------x

1200x = 36000

x = 36000/1200 = 30°

1200----------200

360------------x

1200x = 72000

x = 72000/1200 = 60°

1200----------300

360------------x

1200x = 108000

x = 108000/1200 = 90°

D)

150° = obtuso

30° = agudo

30° = agudo

60° = agudo

90° = Reto
