Question

6* Questão - Valor: 1,0 ponto Calcule o valor dos ângulos nos paralelogramos abaixo: b) c) d) f) B) F 70 >H​

Answer 1

A)  B=180-60=120 graus

C= 60 graus

D= 120 graus

B= 135 graus     A = 45 graus    C = 45 graus   D = 135 graus

B) R + 5 = 180 graus

3x + x - 180 graus

4x = 180 graus

x = 180 / 4

x = 45 graus

C) x + 70 graus = 2x = 10 graus

x + -2 = 10 graus - 70 graus

- x = 60 graus . (-1)

x = 60 graus

D) (2x + 25) + (5x - 20) = 180 graus

7x + 5 = 180 graus

7x = 180 - 5

7x = 175 graus

x = 175/7

x=25

2(25) + 25

50 + 25  

75 graus

5(25) - 20

25 - 20

105° graus

E)

R = T e S = U => R = 5x e S = x

x + x + 5x + 5x = 360 graus

12x = 360 graus

x = 360º/12

x = 30 graus

R = T = 5.30º = 150 graus

S = U = 30 graus

F) 2x + 20 = x + 80 graus

2x - x = 80 - 20 graus

x = 60 graus

G) E = 70 graus

x + 70 = 180 graus

x = 180 - 70 graus

x = 110 graus

Espero ter ajudado!
