Respuesta :

Opposite angles in parallelogram are equal so the answer will be;

2n+30=n+45

2n-n=45-30

n=15


For this case, we have that by definition, in a parallelogram, the opposite angles are congruent, that is, they are equal. So, given the measurements of two opposite angles of a parallelogram, we have:

[tex]2n + 30 = n + 45[/tex]

Clearing "n":

Subtract "n" from both sides of the equation:

[tex]2n-n + 30 = n-n + 45\\n + 30 = 45[/tex]

We subtract 30 from both sides of the equation:

[tex]n + 30-30 = 45-30\\n = 15[/tex]

Thus, the value of n is 15.

Answer:

[tex]n = 15[/tex]
