Question

Os triângulos ABD e CDB são congruentes.
Então X e Y são, respectivamente, iguais a:

a)3 e 5
b)5 e 3
c)3 e 6
d)6 e 3

Answer 1

$\text{Primeiramente obteremos os valores de 'x' e 'y':}\\\\2y+1=11\\\\2y=11-1\\\\2y=10\\\\y=\dfrac{10}{2}\\\\y=5\\\\\\2x=6\\\\x=\dfrac{6}{2}\\\\x=3\\\\\\\\\text{Valores de 'x' e 'y':}\ 3\ \text{e}\ 5.\\\\\text{Alternativa a).}$
