Step-by-step explanation:

$sum \: of \: interior \\ \: angels \: is \: 2340 \: degrees. \\ (n−2)⋅180=2340 \\ 180n - 360=2340 \\ 180n = 2700 \\ n=15 \\ number \: of \: sides=15$

the polygon is 15 sided.

For what values of x and y must ABCD be a parallelogram?

n200080 [17]

Step-by-step explanation:

We know that vertically opposite angles of a parallelogram are equal .

$\angle ABC =\angle ADC\ and \ \angle BAD = \angle DAC$

⇒ $3x^{\circ}=(4x-21)^{\circ} \ and \ 3y^{\circ}=(y+78)^{\circ}$

⇒ $3x^{\circ}-4x^{\circ}=-21^{\circ} \ and \ 3y^{\circ}-y^{\circ}=78^{\circ}$

⇒ $-x^{\circ}=-21^{\circ} \ and \ 2y^{\circ}=78^{\circ}$

⇒ $x^{\circ}=21^{\circ} \ and \ y^{\circ}=39^{\circ}$
