Question

ajuda por favor pessoal rsrs :-)

Answer 1

9y + 16 = 7y + 40
9y - 7y = 40 - 16
2y = 24
y = 24/2
y = 12

A soma dos ângulos = 360
x + x + 9y + 16 + 7y + 40 = 360
2x + 56 + (9*12) + (7*12) = 360
2x + 56 + 108 + 84 = 360
2x = 360 - 248
2x = 112
x = 112/2
x = 56

Answer 2

Resposta do y
9y+16+x=7y+40+x
9y-7y+x-x=40-16
2y=24
y=24:2
y=12
Resposta do x
108+16+x+84+40+x=360
2x+248=360
2x=360-248
2x=112
x=112:2
x=56
