Question

Determine x, sabendo que os ângulos são complementares.

Answer 1

Resposta:

a) 15

b) 36

c) 35

d) 40

Explicação passo-a-passo:

a) 5x + x = 90, 6x = 90, x = 90/6, x = 15

b) x + 18 + x = 90, 2x + 18 = 90, 2x = 90 - 18, 2x = 72, x = 72/2, x = 36

c) 2x + x - 15 = 90, 3x = 90 + 15, 3x = 105, x = 105/3, x = 35

d) x + 10 + x = 90, 2x + 10 = 90, 2x = 90 - 10, 2x = 80, x = 80/2, x = 40
