Question

Calcule o valor de cada angulo das figuras:

Answer 1

Explicação passo-a-passo:

A)

60° + y = 180°

y = 180° - 60°

y = 120°

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

120° + z = 180°

z = 180° - 120°

z = 60°

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

x + 60° + 60° = 180°

x + 120° = 180°

x = 180° - 120°

x = 60°

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

B)

vamos representar o ângulo interno desconhecido do triângulo como incógnita

"y" >>>>>>

30° + 75° + y = 180°

105° + y = 180°

y = 180° - 105

y = 75°

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

75° + x = 180°

x = 180° - 75°

x = 105°
