Question

No paralelogramo abaixo, determine as medidas de x e y.
*

x = 15 e y = 25.
x = 13 e y = 15.
x= 25 e y = 15.
x = 25 e y = 13.

Answer 1

Resposta:

x = 25 e y = 15

Explicação passo a passo:

$3x+20+2x+35=180\\5x+55=180\\5x=180-55\\5x=125\\\\x=\frac{125}{5} \\\\x=25$

$4y+15+7y=180\\11y=180-15\\11y=165\\\\y=\frac{165}{11} \\\\y=15$
