Question

calcule o valor de x​

Answer 1

a) 5x+5+3x+13 = 90°

5x+3x = 90-5-13

8x = 72

x = 72/8

x = 9°

b) 5x-27+x+15 = 90°

5x+x = 90-15+27

6x = 102

x = 102/6

x = 17°

c) 4x-6+2x = 90°

4x+2x = 90+6

6x = 96

x = 96/6

x = 16°

Answer 2

Resposta:

hm

Explicação passo-a-passo:

a) (5x + 5) + (3x + 13) = 90

5x + 3x + 13 + 5 = 8x + 18 = 90

8x = 90 - 18

8x = 72

x = 72 / 8

x = 9

b) 5x - 27 + x + 15 = 5x + x - 27 + 15

5x + x - 27 + 15 = 6x - 12

6x - 12 = 90

6x = 90 - 12

6x = 78

x = 78 / 6

x = 13

c) 4x - 6 + 2x = 4x + 2x - 6

6x - 6 = 90

6x = 90 + 6

6x = 96

x = 96 / 6

x = 16
