Question

45+35+x=180°
80+x=180
X=180-8
X=100

Answer 1

Resposta:

$\rightarrow{a)\:x=100°\:b)x=100}$

$\rightarrow{c)\:x=172\:\:d)\:x=100}$

Explicação passo-a-passo:

$45 + 35 + x = 180° \\ x = 80 - 180° \\ x = 180° - 80 \\ x = \color{blueviolet}{100°}$

$8 0 + x = 180 \\ x = 180 - 80 \\ x = \color{blue}{100}$

$x = 180 - 8 \\ x = \color{magenta}{172}$

$x = 100 \\ \color{purple}{100x}$
