Question

4) Calcule o valor de x, sabendo que os ângulos são suplementares:
a)130° x
b)111° x
c)2x - 40° 3x - 10°
d)12x + 10° 5x
e)2x + 12° 2x + 10°
f)6x + 15° 2x + 5°​

Answer 1

Explicação passo-a-passo:

a)130°x=180°

x=180°-130°

x=50°

b)111°x=180°

x=180°-111°

x=69°

c)2x-40°+3x-10=180°

5x=180°+40°+10°

5x=230°

x=230°/5

x=46°

d)12x+10°+5x=180°

17x=180°-10°

17x=170°

x=170°/17

x=10°

e)2x+12°+2x+10°=180°

4x=180°-22°

4x=158°

x=158°/4

x=39,5

f)6x+15°+2x+5°=180°

8x=180°-20°

8x=160°

x=160°/8

x=20°
